Abstract: Herein disclosed is a method for producing liquid hydrocarbon product, the method comprising disintegrating a hydrocarbon source; pretreating the disintegrated hydrocarbon source; solubilizing the disintegrated hydrocarbon source to form a slurry comprising a reactant molecule of the hydrocarbon source; admixing a biochemical liquor into the slurry, wherein the biochemical liquor comprises at least one conversion enzyme configured to facilitate bond selective photo-fragmentation of said reactant molecule of the hydrocarbon source, to form liquid hydrocarbons via enzyme assisted bond selective photo-fragmentation, wherein said conversion enzyme comprises reactive sites configured to restrict said reactant molecule such that photo-fragmentation favorably targets a preselected internal bond of said reactant molecule; separating the liquid hydrocarbons from the slurry, wherein contaminants remain in the slurry; and enriching the liquid hydrocarbons to form a liquid hydrocarbon product.

Abstract: A method for producing a liquid fuel from a hydrocarbon source. In one embodiment, the method comprises disintegrating a hydrocarbon source, treating the disintegrated hydrocarbon source, solubilizing the disintegrated hydrocarbon source, admixing a biochemical liquor, wherein the biochemical liquor comprises at least one conversion enzyme to form liquid hydrocarbons, separating liquid hydrocarbons, and enriching the liquid hydrocarbons to form a liquid hydrocarbon product.
