摘要:
A process for the conversion of lignin to liquid hydrocarbons comprising: (1) hydrogenolyzing a lignin in the presence of at least one hydrogenolysis catalyst, at a temperature ranging from 250° C. to 350° C., preferably ranging from 290° C. to 320° C., to obtain depolymerized lignin; and (2) hydrodeoxygenating said depolymerized lignin in the presence of a hydrodeoxygenating catalyst to obtain a mixture of liquid hydrocarbons. The resultant liquid hydrocarbons can be used as such (biofuels) for the production of reformulated gasolines, or they can be used for the production of gasolines or oils by conventional refining processes.
