| 摘 要： | 以活性炭（AC）为载体制备了负载型SnCl4催化剂，并添加了不同质量分数BiCl3以及CuCl2，以此研究助剂对催化乙炔氢氯化反应性能的影响。结果表明，5%BiCl3?10%CuCl2?10%SnCl4的催化剂配比对乙炔氢氯化反应活性最高。在乙炔/氯化氢体积比1∶1.1、反应温度170 ℃、乙炔空速60 h-1的反应条件下，乙炔转化率最高可达94%。通过对催化剂的表征发现，助剂的引入抑制了反应过程中S的流失，从而提高了催化剂的稳定性和Sn基催化剂的活性。

| Abstract: | The supported SnCl4 catalyst was prepared using activated carbon as the carrier. Different contents of BiCl3 and CuCl2 were added into SnCl4 catalyst as assistant in order to study the effect of assistant on the catalytic performance of acetylene hydrochlorination. The results showed that when the ratio of BiCl3?CuCl2?SnCl4 was 5%,10%,10%.The catalyst showed the highest activity for acetylene hydrochlorination. The conversion of acetylene can reach 94% under the conditions of hydrogen chloride/acetylene ratio 1∶1.1, reaction temperature 170 ℃ and GHSV(C2H2) of 60 h-1. The characterization results showed that the introduction of additives inhibited the loss of Sn during the reaction and thus improved the stability of the catalyst. Finally, the activity of Sn based catalyst was effectively improved. |
