Abstract
A method and apparatus for producing a solid biofuel from hydrocarbonaceous feedstock is described. The process includes loading a hydrocarbonaceous feedstock into a reactor vessel, adding an aqueous catalyst solution into the reactor vessel, wherein the catalyst solution resides at the bottom of the reactor vessel under the hydrocarbonaceous feedstock position, heating the reactor vessel at or above 170° C. to catalyze a reaction of hydrocarbonaceous feedstock under saturated steam conditions for a time sufficient to yield a polymeric biofuel, and isolating the polymeric biofuel from the reactor vessel.
