| 摘 要： | The effects of catalyst preparation and reaction conditions on thecatalytic activity and selectivity for hydrogenation of carbon dioxide to alcoholsover zeolite supported bimetal catalyst were studied.The results showed that:(1)ethanol easily formed on the zeolite with larger pores and methanol did onthat with smaller pores;(2)when pH value of the ion exchange solution was10,the activity reached the maximum;(3)the optimum Cu/Ru mole ratio was3;(4)the influence of reation conditions such as temperature,pressure andH_2/CO_2 mole ratio on the topic reaction was greater.
