常压下四氯化硅冷氢化制备三氯氢硅催化剂性能考察

Investigate the Performance of Trichlorosilane Catalyst Prepared by Tetrachloride Silicon Cold Hydrogenation under Atmospheric Pressure

采用镍、铜、镧和铁为活性组分制备单一活性组分催化剂和混合活性组分催化剂，利用反应评价装置，在常压条件下对各催化剂催化性能进行考察，结果表明，单活性组分和混合组分催化剂的转化率和选择性均达到加压冷氢化法水平，混合组分催化剂的稳定性优于单一活性组分催化剂。

Nickel copper, lanthanum and iron were used as the active components to prepare single active component catalysts and mixed active component catalysts. The catalytic performance of various catalysts were investigated under atmospheric pressure by response evaluation device. The results show that conversion and selectivity of single active component and mixed active component catalysts have reached the level of pressurized cold hydrogenation. The stability of mixed active component catalysts is better than sinzle active component catalysts.
