Abstract: A process for producing liquid hydrocarbon products from a biomass feedstock is provided. The process comprises:contacting the feedstock with one or more hydropyrolysis catalyst compositions and molecular hydrogen to produce a product stream comprising hydropyrolysis product that is at least partially deoxygenated;hydroconverting said hydropyrolysis product in the presence of one or more hydroconversion catalyst compositions to produce a vapour phase product comprising substantially fully deoxygenated hydrocarbon product,wherein one or both of the hydropyrolysis catalyst composition and the hydroconversion catalyst composition is produced in a process comprising incorporating one or more metals selected from those of groups 6, 9, and 10 of the periodic table, into a shaped support; and incorporating one or more coordinating organic compounds into said shaped support, thus forming a catalyst precursor; and then either (i) treating the catalyst precursor in the presence of hydrogen and sulfiding it or (ii) calcining the catalyst precursor.

Abstract: A process for converting biomass to products is described. Biomasss is contacted with hydrogen in the presence of a fluidized bed of hydropyrolysis catalyst in a reactor vessel under hydropyrolysis conditions; and products and char are removed from the reactor vessel. The products leave the fluidized bed at an exit bed velocity, the char has a settling velocity that is less than the exit bed velocity and hydropyrolysis catalyst has a settling velocity that is greater than the exit bed velocity.
