PROCESS FOR THE CONVERSION OF LIGNIN TO LIQUID HYDROCARBONS

摘要

Process for the conversion of lignin to liquid hydro- carbons comprising: subjecting the lignin to hydrogenolysis 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, so as to obtain depolymerized lignin; subjecting said depolymerized lignin to hydrotreating so as to obtain a mixture of liquid hydrocarbons. Said 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 of gas oils through conventional refining processes.
