A PROCESS FOR PRODUCING SYNTHETIC FUELS FROM WASTE AND OTHER MATERIALS

摘要

A method for producing hydrocarbons or oxygenates for use as a synthetic fuel source from suitable material, the method including: providing a feedstock stream comprising solid and/or liquid and/or gaseous material under pressure to a mixing vessel at a predetermined feed rate; injecting a stream of a reactant gas capable of dissolving in the feedstock into the feedstock stream for mixing; transferring a stream of feedstock and gas reactant mixture to a reaction vessel downstream therefrom; subjecting the feedstock and gas mixture in the reaction vessel to at or near supercritical conditions; wherein the solubilised material is broken down in the reaction vessel into a distribution of molecular weight fractions, and wherein the reactant gas selectively adds or subtracts from the molecular weight fractions to provide a hydrocarbon or oxygenate of predetermined chain length suitable as an alternative fuel.
