Hemp Biodiesel vs Diesel: Compiled from: Greenfuels and NBB

Overall ozone (smog) forming potential of biodiesel is less than diesel fuel. The ozone forming potential of the speciated hydrocarbon emissions was nearly 50 percent less than that measured for diesel fuel.1

Sulfur emissions are essentially eliminated with pure biodiesel. The exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel were essentially eliminated compared to sulfur oxides and sulfates from diesel.1

Criteria pollutants are reduced with biodiesel use. The use of biodiesel in an unmodified Cummins N14 diesel engine resulted in substantial reductions of unburned hydrocarbons, carbon monoxide, and particulate matter. Emissions of nitrogen oxides were slightly increased.1

Carbon Monoxide: The exhaust emissions of carbon monoxide (a poisonous gas) from biodiesel were 50 percent lower than carbon monoxide emissions from diesel.1

Particulate Matter: Breathing particulate has been shown to be a human health hazard. The exhaust emissions of particulate matter from biodiesel were 30 percent lower than overall particulate matter emissions from diesel.1

Hydrocarbons: The exhaust emissions of total hydrocarbons (a contributing factor in the localized formation of smog and ozone) were 93 percent lower for biodiesel than diesel fuel.1

Nitrogen Oxides: NOx emissions from biodiesel increase or decrease depending on the engine family and testing procedures. NOx emissions (a contributing factor in the localized formation of smog and ozone) from pure (100%) biodiesel increased in this test by 13 percent. However, biodiesel's lack of sulfur allows the use of NOx control technologies that cannot be used with conventional diesel. So, biodiesel NOx emissions can be effectively managed and efficiently eliminated as a concern of the fuel's use.1

Biodiesel reduces the health risks associated with petroleum diesel. Biodiesel emissions showed decreased levels of PAH and nitrited PAH compounds which have been identified as potential cancer causing compounds. In the recent testing, PAH compounds were reduced by 75 to 85 percent, with the exception of benzo(a)anthracene, which was reduced by roughly 50 percent. Targeted nPAH compounds were also reduced dramatically with biodiesel fuel, with 2-nitrofluorene and 1-nitropyrene reduced by 90 percent, and the rest of the nPAH compounds reduced to only trace levels.1

Environmental & Safety Information:

Acute Oral Toxicity/Rates: Biodiesel is nontoxic. The acute oral LD50 (lethal dose) is greater than 17.4 g/Kg body weight. By comparison, table salt (NaCL) is nearly 10 times more toxic.1

Skin Irritation: A 24-hr. human patch test indicated that undiluted biodiesel produced very mild irritation. The irritation was less than the result produced by a 4 percent soap and water solution.1

Aquatic Toxicity: A 96-hr. lethal concentration for bluegill of biodiesel grade methyl esters was greater than 1000 mg/L. Lethal concentrations at these levels are generally deemed "insignificant" according to NIOSH (National Institute for Occupational Safety and Health) guidelines in its Registry of the Toxic Effects of Chemical Substances.1

Biodegradability: Biodiesel degrades about four times faster than petroleum diesel. Within 28 days, pure biodiesel degrades 85 to 88 percent in water. Dextrose (a test sugar used as the positive control when testing biodegradability) degraded at the same rate. Blending biodiesel with diesel fuel accelerates its biodegradability. For example, blends of 20 percent biodiesel and 80 percent diesel fuel degrade twice as fast as #2 diesel alone.1

Flash Point: The flash point of a fuel is defined as the temperature at which it will ignite when exposed to a spark or flame. Biodiesel's flash point is over 300 deg. Fahrenheit, well above petroleum based diesel fuel's flash point of around 125 deg. Fahrenheit. Testing has shown the flash point of biodiesel blends increases as the percentage of biodiesel increases. Therefore, biodiesel and blends of biodiesel with petroleum diesel are safer to store, handle, and use than conventional diesel fuel.1

 

Ohhh.... Do i love talking about this subject. I have an old Mercedes Benz myself and was looking around on hempcar.org. I WANT ONE.

A Benz on Hempfuel that is.....

Diesel Fuel From Seed Oil

"The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in the course of time as important as petroleum," declared Rudolf Diesel in 1912.

Alcohol fuels will not power diesel motors, but vegetable oil will. According to the DOE, "Biodiesel's major advantage is that it is environmentally clean. Unlike conventional diesel fuel, biodiesel contains neither sulfur nor aromatics. Aromatics contribute to particulate emissions.... Biodiesel is biodegradable."

In 1990, a French company displayed an engine that ran on peanut oil. At the end of World War II, the Japanese navy stored soybean oil to fuel the 65,000-ton battleship Yamoto.

Farmers are intrigued because unlike ethanol, vegetable-oil extraction requires no distiller's license. The process requires less water and energy than ethanol production, and produces a high-protein meal as a byproduct. Oilseed fuels have a low sulfur content, are safe to store and do not cause skin ailments.

In the authoritative Oil Crops Of The World, oilseed-energy expert G.R. Quick reports that, "Initially, engine performance has been encouraging with most of these candidate diesel-fuel alternatives. Short-term tests on both DI [direct injection] and IDI [indirect injection] engines show that power output, torque and brake thermal efficiency on oilseed fuels were similar to those when the same engine was used on diesel fuel. Fuel consumption is usually somewhat higher due to the lower heat-energy of the oil."

The problems with using vegetable oils to fuel direct-injection engines included start-up problems in cold weather and fouled injector tips in the engines after sustained operation. Technical aids can help with the starting problems, but the fouled injector tips are a result of high viscosity, and this could be a problem for hemp oil: Carbon builds up in the injector holes, interfering with the spray pattern of the fuel and affecting the combustion. Engine power declines and exhaust smoke and engine misfiring increase.

Viscosity is a measure of the oil's thickness, particularly of its resistance to flow. Vegetable oil flows faster at room temperature, for example, than petroleum motor oil does. Relatively high viscosity is characteristic of vegetable-oil fuels (except for castor oil). One response is frequent maintenance, such as replacement of the injector tips. Another strategy has been to lower the oil's viscosity by blending it with mineral distillates. Also, heating oils lowers their viscosity; fuel heaters can use engine coolant as a heating medium.

Blending and heating do not solve all these problems, and viscosity is not their only cause. Oils that have similar viscosities can produce injection-tip fouling at different rates. Oils with high unsaturated fats, such as linseed oil, are the most conducive to injector-tip fouling. An engine that will run for 100 hours on rapeseed or sunflower oil will last only about 10 hours on linseed oil. Hemp oil, unfortunately, is also high in unsaturated fats, and would seem unlikely to be competitive with other oils as a source of biodiesel fuel for direct-injection engines.

In the DI engine, fuel is injected directly into a combustion chamber. However, in the indirect-injection engine, the combustion takes place in an antechamber. Large tractors tend to be DI engines, while IDI engines are more elaborate and quieter.

Indirect-injection engines run on vegetable-oil fuels without significant problems. South African engineers have run unmodified Deutz tractors with IDI engines for 3,000 hours, with some attention to fuel filtration. Quick also reports similar results with Caterpillar tractors in Brazil. The two manufacturers have qualified their warranties in those countries, respectively, for machines operated on vegetable fuels.

Australian engineers have confirmed that even highly unsaturated linseed oil will fuel an IDI engine without problem, after testing an engine for 200 hours. Hemp oil, used as a biodiesel fuel, should be capable of operating indirect-injection engines without abnormal component wear to the engine.

I don't understand. This might come like a stupid quetion but uhm....

Besides the obvious OIL "problem". Why are not utelizing these resources more?

I have an OLD Volkswagon diesel Van. i would love to run it on hemp

Ciao for now

So it's definately possible to run your VW Diesel on Hemp/ linseed Oil. It takes NO to little alterations on your engine. Look on the internet for mechanics advertising with Linseed engines.

I Myself am actually looking into it too.

hi, seero

i think you are walking on the right side

yeah, man....you don't know how long i am trying to get infos about H2 generators of electricity...

and the bad notice is that they are ok, but they do not sell it to private persons.

you (and I and so many people) would say

WHAT THE f**k?

yes, wtf friend...

btw we know of cars that moves with oil of hemp/linseed

yeahhhhhhh it is so cooooooooooolllllllll

my regards tooooooooooo

Allmost any 'standard' diesel can run on linseed oil. The mixture is amazing too. your exhaust just smells like you work for MCd's. I say drive linseed if you can!

I got bikini lines on my bud...

Hemp Oil Fuels & How to Make Them

Introduction of Hemp Bio Diesel maybe the liquid fuel of the future. Hemp is a high yield C-4 photosynthesis plant. Hemp can boast a higher oilseed yield than any of today's oilseed crops (soy, canola or safflower).

Thirty years ago soy beans were a joke to American farmers. Who would have guessed that in thirty years soy beans would become the largest oil and protein crop in American farming. Right now Hemp farming is a joke to American farmers. Who knows what the next thirty years will do to American Hemp farming. Hemp fuels are yet another benefit of Domestic Industrial Hemp Farming. As we enter 1997 more than ten states will be considering Industrial Hemp Farm Bills. In the meantime, Hempseed must be grown out side the country. The major part of the cost of the inexpensive Hempseed is transportation from across the globe. The seed to produce a gallon of Hemp-seed oil can cost up to $100. All foreign production and shipping plans are doomed to high costs. I look forward to the days when a farmer can produce his own hempseed oil fuel as low as a dollar a gallon.

The following formula for making Hemp Diesel Fuel will work nicely to make small quantities of fuel to run the sound stage at your Hemp Rally this summer. A 4 kilowatt diesel generator uses around one liter an hour .Imagine walking to the microphone and saying, "The sound of my voice is coming to you with the power of Hemp Fuel !". Seeing is believing. I'll drive you around the state capital, Senator, In my Hemp Fueled Vehicle!

Bio Diesel is not a new fuel. The DOE and USDA have provided funding for research for years. The Biomass Conference of The Americas in Burlington Vermont had over a dozen papers presented on all aspects of Hemp as an oilseed cultivars. Lets get on with it!

How to Make Bio Diesel Titration of Free Fatty Acids. Measure Free Fatty Acid content of your oil: Mix 1 ml oil with 10 ml Isopropyl alcohol = 2 drops phenolthalian solution (available in a hobby shop chemistry set suppliers). Drop-wise add 0.1% lye solution ( 1 gm lye in one liter water ) until the solution stays pink for 10 seconds. (20 drops = 1 ml) Record the milliliters of 0.1% lye solution used.

Methanol You will need 200 ml of methanol per liter of Hemp Seed oil. Methanol may be purchased as Drigas available at most automotive stores, read the label for methanol. Also Methanol is available from racing stores. Avoid hardware store methanol (wood alcohol) as it mat contain excessive water content.

Sodium Methoxide For each liter of hemp seed oil you need one gram of granular solid lye for each ml of 0.1% lye solution used in titration of free fatty acids plus 3.5 grams. Completely dissolve the proper amount of Lye in the methanol (Red Devil Lye can be purchased from the Grocery Store). This combined mixture makes sodium methoxide.

Mixer The type of mixer depends on the size of the batch. A blender works fine for a small batch. An electric drill and paint mixer on an extended shaft works well in a 5 gallon bucket. An electric light dimmer switch provides a good speed control.

Transesterfication Once the lye catalyst is dissolved completely so that there is no sediment, then the oil may be added to the methanol lye mixture while mixing continuously. At first the mixture becomes thicker, then thinner as the reaction proceeds. Collect samples every 5 minutes with an eye dropper into a test tube or clear container. The Mixture will separate into a light top layer of bio diesel and a darker bottom layer of glycerin, soap and catalyst. Continued mixing 30 - 60 minutes until the yield remains constant. Then stop mixing. Go have lunch. When you come back it will have settled into two distinct layers. You have just made what could be the fuel of the future for a self reliant society. Let the mixture settle for at least 8 hours. Pour off and save the bio diesel top layer into another container. A clear funnel bottomed container is helpful.

Rinsing The raw Bio Diesel that you have just produced may have some catalyst, alcohol, and glycerin remaining which could cause engine problems, so for long term engine reliability this raw fuel should be rinsed with water. Gently at first then more vigorously rinse with water until the rinse water is clear and the pH of the rinse water is the same pH as the supply water. Settle, Decant.

Drying Water in the bio Diesel makes cloudy so it must be carefully heated. At 100 C most of the water coalesces and falls to the bottom. This water must be completely removed from the bottom of the container before heating to higher temperature.

CAUTION! Wear protective clothing and eyewear. FAILURE TO REMOVE THIS WATER BEFORE FURTHER HEATING CAN CAUSE VIOLENT ERUPTION OF HOT LIQUID!

Once all water has been removed then heat the bio diesel to 300 f (150 c) to complete dryness. Cool, filter, and store bio diesel in a well marked dry closed container. 100% HEMP DIESEL FUEL (HEMP OIL METHYL ESTER - HOME FUEL)

This fuel may be mixed in any ratio with petroleum diesel. Dynamometer tests indicate full power output with up to 75% reduction in soot and particles. No engine modification is needed to burn bio diesel fuel.

Other Oil Feedstocks Hemp Seed Oil at present is too expensive to drive across the country. That is not the object of this article. Our purpose is to demonstrate proof of feasibility of this fuel concept. The time is now to give hemp a chance. The small quantities of Hemp Diesel Fuel can play a powerful role in educating ourselves and the policy makers about the hope in hemp.

For other readers the question will be raised. What else can I use can I use as a feedstock that is cheaper between now and domestic hemp seed crops? Soy, Sunflower, Canola, and Safflower oils are being used in field testing programs right now.

the succes of introduction depends on how much profit it makes
(demand side)
or
the succes depends on how many customers start to buy hempoil
(question side)
Soya became succesful after patents, genetic manipulation.
profit secured, investors, succes..
lets do it different, the only way to a better world is less consuming.
start with yourself, your friends etc. New thinking..
work together with big companies like shell, otherwise the will kill your idea..
marketing, good will, knowledge by the people.
The crisis makes new ideas profitable..
it 's the time for changes..
