A PROCESS FOR PRODUCING A HYDROCARBON PRODUCT FROM LIGNIN OIL

A process for producing a hydrocarbon product from a lignin oil， said lignin oil having an oxygen content of 10-30 wt-%， an average weight molecular weight of 500-800 g/mol with a polydispersity of 2， a heating value of 25-35 MJ/kg， a water content of 0-1.5 wt-%， a sodium content of 400-500 ppm， a potassium content of 50-100 ppm， a sulfur content of 1-2.5 wt-% and a total acid number of 110-125 mg KOH/g oil， wherein the process for producing the hydrocarbon product comprises the steps of treating the lignin oil in a rector in the presence of one or more of a hydrodesulfurization catalyst selected from NiMo on alumina or CoMo on alumina; or a hydrodesulfurization and cracking catalyst selected from NiMo on zeolite or CoMo on zeolite， or a hydrodeoxygenation and cracking catalyst selected from NiO on zeolite， zeolite alone or combinations thereof， or a hydrodeoxygenation catalyst selected from Ni/NiO， Cu/Cr， Pd/Cu， or Pt on a support material， such as chromite and/or alumina and/or zirconia and/or graphite and/or carbon and/or silica; or combinations thereof， and applying a H 2 pressure of 30-160 bar， preferably 50-150 bar， a gas to oil ratio (GTO) of 200- 2000 l/l， preferably 500-1500 l/l， at a temperature of 290-400 °C， preferably 300-360 °C， and with a liquid hourly space velocity (LHSV) of 0.25-2 h-1 and preferably 0.5-1 h-1 followed by cooling the reaction product from the reactor to 20-30 °C， and separating the reaction product by phase separation， into a gaseous phase， a liquid hydrocarbon product phase， and a water phase， thereby obtaining the hydrocarbon product， and a hydrocarbon product.
