摘　　要：针对四氯化硅氢化反应,采用等体积浸渍法制备了以HZSM-5为载体,金属氯化物为活性组分的负载型四氯化硅氢化反应催化剂,考察了催化剂的催化性能,并进行了相应表征。结果表明,碱土金属氯化物对四氯化硅氢化过程有良好的催化效果,在BaCl2负载质量分数为1%和反应温度850℃条件下,反应最高转化率为20.20%,选择性83.01%。Using HZSM-5 as the support and different metal chlorides as the active components, the different supported catalysts for hydrogenation of silicon tetrachloride to trichlorosilane were prepared by impregnation method. The as-prepared catalysts were characterized by XRD, XPS and BET. The activity of the catalysts was investigated. The results showed that the chlorides of alkaline earth metal, especially barium, exhibited better catalytic activity for the hydrogenation of silicon tetrachloride; the maximum conversion of silicon tetrachloride of 20.22% and the highest selectivity to trichlorosilane of 83.01% were attained under the condition of reaction temperature 850 ℃ and BaCl2 loading 1% （mass fraction）
