The present invention relates to processes for extracting lipid from vegetative plant parts such as leaves, stems, roots and tubers, and for producing industrial products such as hydrocarbon products from the lipids. Preferred industrial products include alkyl esters which may be blended with petroleum based fuels.

Systems and methods associated with biomass decomposition are generally described. Certain embodiments are related to adjusting a flow rate of a fluid comprising oxygen into a reactor in which biomass is decomposed. The adjustment may be made, at least in part, based upon a measurement of a characteristic of the reactor and/or a characteristic of the biomass. Certain embodiments are related to cooling at least partially decomposed biomass. The biomass may be cooled by flowing a gas over an outlet conduit in which the biomass is cooled, and then directing the gas to a reactor after it has flowed over the outlet conduit. Certain embodiments are related to systems comprising a reactor and an outlet conduit configured such that greater than or equal to 75% of its axially projected cross-sectional area is occupied by a conveyor. Certain embodiments are related to systems comprising a reactor comprising an elongated compartment having a longitudinal axis arranged substantially vertically and an outlet conduit comprising a conveyor.

A method to create a natural charcoal briquette is described herein. A wood material is collected and impurities are removed from the wood material. The wood material is dried at a temperature in a range of approximately 150° C. to approximately 200° C. to reach a moisture level in a range of approximately 3.7% to approximately 5.0%. The dried wood material is compressed in a shaped mold at approximately 300° C. and under 40 tons of pressure to form a charcoal briquette. The charcoal briquette is carbonized at a temperature in a range of approximately 700° C. to approximately 800° C. in a range of approximately 14 days to approximately 17 days. The charcoal briquette is then cooled for approximately 2 days prior to use or packaging.
