Abstract: Systems and methods are provided for reducing hydrogen consumption during deoxygenation of bio-derived (or at least partially bio-derived) feedstocks. The reduced hydrogen consumption is achieved by performing the deoxygenation in the presence of a bulk multimetallic catalyst and/or in the presence of a base metal dewaxing catalyst having reduced metal stack heights. Additionally, due in part to being able to reduce or minimize hydrogen consumption, the heat release during deoxygenation can also be reduced, thus allowing a smaller catalyst volume to perform deoxygenation.
