Abstract

Abstract Hydrogenation of carbon dioxide to C 3 and C 4 paraffins (LPG) was studied by using hybrid catalysts composed of Zr-modified Cu–Zn catalyst with Pd-modified β zeolite. Various factors that affect catalyst activity, including reaction temperature, space velocity, pressure, and the ratio of H 2 to CO 2 were investigated thoroughly. The hybrid catalysts exhibited stable activity over 100 h and extraordinary high selectivity of LPG synthesis ( ...
