摘要： A process for hydrogenating acetylene in hydrogen chloride gas using the catalytic palladium supported on silicon carbide carrier whose iron content is specified to be not more than 1,000 ppm. The catalyst has the advantages of enhancing the conversion of acetylene into ethylene, improving the selectivity of ethylene, and retaining catalytic activity over a long time at a large space velocity. This process can be effectively applied to the hydrogenation of acetylene in hydrogen chloride gas separated from the thermally decomposed products of 1,2-dichloroethane which occurs in the production of vinyl chloride; namely, the hydrogen chloride gas that contains thus hydrogenated acetylene (ethylene) can be recycled in such an effective way that 1,2-dichloroethane can be produced economically.
