WebAug 7, 2024 · For semi-hydrogenation of acetylene in excess of ethylene, the prepared Ni1Cu2 trimer catalyst showed excellent catalytic performance in activity, selectivity and stability. The catalyst achieved complete conversion of acetylene at about 170 °C and maintained 90% ethylene selectivity and stability for more than 350 hours. WebNo trimer formation was observed in the presence of the FeAA catalyst. The percentage of the trimer group and the trimer/urethane content were found to be increased with increasing the stochiometric ratio or DBTDL concentration. The thermal decomposition of the copolyurethanes in an inert atmosphere was studied by means of thermogravimetry (TG).
