A preferred embodiment of the present invention is directed generally to a composition of matter and, more specifically, to a composition comprising a petroleum substitute produced from renewable, herbaceous plant-based sources through a solvent extraction process. The plant sources are typically hydrocarbon-bearing plants capable of producing significant quantities of liquid terpenes such that the process of extracting hydrocarbons from the plant material is economically viable. In a preferred embodiment of the invention, the plant species is Euphorbia tirucalli, a species that contains relatively large quantities of relatively low molecular weight hydrocarbons. A raw plant biomass is milled and formed into a batt of plant material having generally uniform properties. Naturally occurring hydrocarbons found in the plant material are then extracted using an organic solvent extraction process. The extracted hydrocarbon oils are then separated from the solvent and may be used as a petroleum substitute, while the solvent may be reused in the extraction operation. |
