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. Various aspects of such method/process are also discussed.
