Many oil refineries accross America are spewing cancer-causing benzene pollutants above the federal threshold!
Hemp yields about 22 gallons of oil per acre. The oil can be used alone or with methanol to serve as bio-diesel fuel, or it can be mixed with petro-diesel. Bio-diesel fuel produces full engine power with much lower emissions (and no sulfur) than does petro-diesel. The latter has a cetane rating (CR) of about 40. The CR of hempseed oil is 60 to 100. Sunflower, safflower, and rapeseed yield only up to about 110 gallons oil/acre.
Biofuel is easily produced by reacting methanol with sodium hydroxide to produce sodium methoxide. Use 200 ml methanol and 3.5 gr NaOH per liter of vegetable oil. The mixture is stirred for one hour, then left to settle for several hours. The products are biodiesel (upper layer) and glycerine soap. Filter the biodiesel (5 microns) before using it. Another method is even simpler: blend 10-40% kerosene with vegetable oil; 20% kerosene produces a reliable mixture throughout a wide range of ambient temperatures. Unadulterated or unreacted vegetable oil also can be used, but the engine must be started and cooled down using diesel or biodiesel. Therefore a two-tank system and switch valve is required.
Hemp stalks can be converted to ethanol (with about 20% efficiency by fermentation of hydrolyzed cellulose), into methane (by digestion of the stalks, with 50% efficiency), into producer gas (by thermal gasification at 85% efficiency) and into methanol (by pyrolysis of the stalks, or from producer gas). It is estimated that hemp biomass can yield an equivalent of 1,300 gal/acre of vehicle fuel. Chopped stalks also can be used directly as a boiler fuel.
Advantages Of Using Hemp Biofuels
As a carbon neutral resource, the plant ingests carbon dioxide (CO2) very quickly, even faster than trees. Plus, carbon dioxide emissions from biodiesel is reabsorbed through the process of photosynthesis in plants. So, in addition to pulling toxins from the soil, the hemp plant can essentially “scrub” CO2 from the air we breathe.
When growing hemp, it returns about 70% of its required nutrients back into the soil, which means this crop requires much less fertilizer to grow. Less fertilizers means cleaner water supplies.
Creating a renewable resource crop which can restore the soil to health, pull toxins from the ground, air and water, while creating a viable energy source may sound like the American Farmer’s dream come true, however, it doesn’t come without its own set of challenges.
