| 摘 要： | 采用Au(en)2Cl3作前驱体，制备了用于乙炔氢氯化反应的载Au催化剂，并采用N2-吸附、XRD、TEM进行了表征。在常压固定床反应器中详细考察了Au的价态、载体、Au负载量、碱金属助剂对Au催化剂活性的影响。结果表明，催化乙炔氢氯化反应的载Au催化剂的活性组分主要以离子态Aun+存在。采用椰壳质活性炭(ACS)为载体、KCl为助剂、Au负载量为1%（质量分数）时，载Au催化剂Au-K/ACS具有较高分散度，平均粒径为2.3nm。以Au-K/ACS作为催化剂，在温度180℃、空速120h-1、V(HCl)/V(C2H2)=1.1时，乙炔氢氯化反应的转化率可达98%以上，氯乙烯选择性不低于99.5%；在空速为2000h-1时，该催化剂仍具有较好的稳定性。
