摘要
用共沉淀法制备CoO-Fe_2O_3-CuO/SiO_2催化剂,在微分反应器上对其催化活性进行考察,测试压力、温度、空速等诸因素的影响。获得在CO/H_2=1:2.270℃、20atm。空速为4300ml/g-Cat.hr条件下,CO转化率为78.9％,液化石油气的选择性较高。
We prepared the following catalyst by coprceipitation: CoO-Fe_2O_3-CuO/SiO_2. The catalystic for carbon monoxide hydrogenation was measured in a microreactor system. The effects of pressure, reaction temperature and space velocity on the activity and selectivity of Co-Fe-Cu/SiO catalyst were investigated.Under the conditions: CO/H_2 molar ratio: 1: 2, reaction temperature: 270℃ C,total pressure: 20 atm, and space velocity:4300ml/g-cat.hr,CO conversion rate is 78.9% and considerable selectivity of LPG was achieved.
