Bloom medicinals jobs5/2/2024 All these processes must be carbon neutral in order to substantiate such a claim. It is important to consider all that is involved in creating the fuel from cultivation to harvest to fuel production. Hemp could quickly surpass pulpwood or kenaf in producing greater biomass tonnage per acre annually in more areas of the USĪre Industrial Hemp Biofuels Carbon Neutral?Ĭlaims have been made suggesting that hemp biofuels are carbon-neutral the amount of CO2 absorbed during the growing process is offset by the amount of CO2 released during use.Due to its high cellulose content, hemp has an estimated 540% energy gain compared to corn’s 34%.Hemp is 80% cellulose, making it low-moisture, herbaceous and woody.Hemp on average produces nine dry tons per acre.How Industrial Hemp Biofuel Compares To Other Sources Methane, the major ingredient of natural gas and close relative of methanol, is produced by the use of a biodigester to capture the gas under optimum anaerobic conditions to create hemp biogas. They are an excellent alternative to wood since they produce similar amounts of heat and ash content but are not corrosive. Hemp pellets are made from the woody core of the plant, known as the shiv or hurd. It is possible that hemp biomass conversion may become a replacement for fossil fuels. It is the most efficient process for hemp biomass conversion with a 95.5% feed-to-fuel efficiency. This keeps the material from catching fire. Pyrolysis, another possible source, is a process where high heat is applied to organic matter such as hemp, without an oxygen source. Dry distillation is the main process used to create hemp methanol, a by-product of which is charcoal.Molecular sieves are deployed to increase the concentration of ethanolĪlso known as wood alcohol, it is produced from the woody, pulp plant material.The ethanol must be extracted through distillation.The sugar solution must go through the fermentation process.The sugar materials must be separated from the lignin, a complex polymer responsible for the strength of the cell walls of plants.Cellulase, an enzyme that converts cellulose into glucose, is required to break down the molecules into sugars.It must be pre-treated to make the cellulose content suitable for hydrolysis.In order to create hemp ethanol, a process called cellulolysis is required. The cost should decrease with an increase of acreage both in the US and in other countries.Įthanol is derived from sugars and starches of plants.Because hemp seed oil is a highly desirable commodity for a variety of uses, this keeps the price of the oil prohibitively high.It is ten times less toxic than salt with a flashpoint of 300☏.įYI: regular diesel has a flashpoint of 125☏ which makes the transportation of biodiesel much safer Why Isn’t Hemp Biodiesel More Widely Used?.You can use biodiesel in any diesel engine.The only area in which it does not outperform conventional diesel is in oxidation stability which can be rectified through the addition of anti-oxidants. Hemp meets the American and European standards for biodiesel quality and appears to be superior to other plant based products.Hemp doesn’t require the expensive drying required of corn and sugar.This exceeds the output of soybeans, sunflowers, peanuts or rapeseeds. Hemp can produce upwards of 800 liters of biodiesel per hectare per year.The end result is raw biodiesel and raw glycerol which then undergo a cleaning process. That is a process where reactants are mixed together fatty acids, alcohol and a catalyst such as sodium or potassium methanolate. Hemp seeds contain around 30% oil which can be transformed into biodiesel for vehicles, using transesterification.
