Conversion of biomass into a liquid hydrocarbon material

The present invention provides a process for producing liquid hydrocarbon products from at least one of a biomass-containing feedstock and a biomass-derived feedstock, said process comprising the steps of: a) contacting the biomass-containing feedstock and/or biomass-derived feedstock with a hydropyrolysis catalyst composition and molecular hydrogen in a hydropyrolysis reactor vessel at a temperature in the range of from 350 to 600°C, a pressure in the range of from 0.50 to 7.50MPa and a WHSV in the range of greater than 2.0 kg(biomass)/hour/kg(catalyst), to produce a product stream comprising a partially deoxygenated hydrocarbon product, H2O, H2, CO2, CO, C1 - C3 gases, char and catalyst fines; b) removing all or a portion of said char and catalyst fines from said product stream; c) cooling the remaining product stream to a temperature in the range of from 150 to 400°C; and d) hydroconverting all or a portion of said partially deoxygenated hydrocarbon product in a hydroconversion reactor in the presence of one or more catalyst compositions suitable for hydrodeoxygenation and aromatic saturation of the partially deoxygenated hydrocarbon product in the presence of H2O, CO2, CO, H2, and C1 - C3 gas generated in step a), to produce a vapour phase product comprising a C4+ hydrocarbon product, H2O, CO, CO2, and C1 - C3 gases.
