Abstract
- A series of Au–Sn/AC catalysts for acetylene hydrochlorination were prepared by an incipient wetness impregnation method and characterized by BET, XPS, TEM, TPR, XRD, ICP-AES and TPD techniques. It is indicated that Au1Sn1/AC catalyst shows the highest activity and stability with the 95% acetylene conversion after 48 h reaction under the conditions of 170 °C and an acetylene gas hourly space velocity of 720 h −1 . The Sn additive can make the Au species dispersed well and weaken the occurrence of coke deposition, as well as inhibit the reduction of Au 3+ to Au 0 , thereby improving the catalytic activity and stability.
