Embodiment 1
[0009] First, 3.44g of copper chloride and 4.28g of sodium hypophosphite were dissolved in 25.0g of deionized water under stirring at room temperature, and then the solution was impregnated into 23g of activated carbon carrier and dried at 60°C; then the dried The dried precursor is loaded into a reactor, roasted at 250° C. for 60 min in a nitrogen atmosphere, and drops to room temperature in a nitrogen atmosphere to obtain a catalyst precursor; finally, 20 g of 5% BaCl 2 The solution was vacuum impregnated into the precursor and dried at 120 °C. The resulting sample was named A. Catalyst A is used in the reaction of preparing vinyl chloride by hydrochlorination of acetylene, the conversion rate of acetylene is 64% at 170°C, and the selectivity of vinyl chloride is 53%.
Embodiment 2
[0011] The preparation process is the same as that of catalyst A, except that the amount of sodium hypophosphite is changed to 6.43 g, and other conditions remain unchanged, and the obtained sample is named B. Catalyst B is used in the reaction of preparing vinyl chloride by hydrochlorination of acetylene, the conversion rate of acetylene is 64% at 170°C, and the selectivity of vinyl chloride is 53%.
Embodiment 3
[0013] The preparation process is the same as that of Catalyst A, except that the calcination temperature of the precursor is changed to 400°C, and other conditions remain unchanged. The obtained sample is named C. Catalyst C is used in the reaction of preparing vinyl chloride by hydrochlorination of acetylene, the conversion rate of acetylene is 66% at 170°C, and the selectivity of vinyl chloride is 56%.
