Abstract:
1. A method of producing a petroleum substitute by extracting naturally occurring hydrocarbons from woody tree material, said method comprising the steps of: a. preparing a plurality of solvent-permeable wood particles by applying compressive and shearing forces to a raw biomass of the woody tree material; b. extracting hydrocarbons from the biomass of woody tree material by contacting the wood particles with a solution of organic solvents comprising at least one non-polar organic solvent and at least one polar organic solvent; c. recovering a mixture comprised of the solvents and the extracted hydrocarbons; and, d. separating the extracted hydrocarbons from the solvents to produce the extract.
