Semi-Hydrogenation of Acetylene to Ethylene Catalyzed by Bimetallic CuNi/ZSM-12 Catalysts

The purpose of this work is to develop a low-cost and high-performance catalyst for the selective catalytic hydrogenation acetylene ethylene. Non-precious metals Cu Ni were selected as active ingredients study. Using ZSM-12 carrier, Cu-Ni bimetallic catalysts CuNix/ZSM-12 (x = 5, 7, 9, 11) with different Ni/Cu ratios prepared by incipient wetness impregnation method. total loading 2 wt%. Under optimal reaction conditions, conversion was 100%, ethylene selectivity 82.48%. CuNi7/ZSM-12 in exhibits good performance semi-hydrogenation low cost has potential industrial application.
