A study of the selective catalytic hydroconversion of biomass-derived pyrolysis or fermentation liquids using propylamine and acetic acid as model reactants

Abstract

Silica-supported P or In modified Ni catalysts were active in the hydrodenitrogenation (HDN) and hydrodeoxygenation (HDO) of reactant propylamine (PA) and acetic acid (AA), respectively, in which reactants were selected to model platform molecules of biomass origin. The undesired CC hydrogenolysis activity of supported Ni catalyst, resulting in low value gaseous products, could be reined by the modification, generating silica-supported Ni2P and Ni2In active phases.
