High temperature chlorination catalyst

摘要

The present invention relates to a novel catalyst system for chlorination of hydrocarbons either by oxyhydrochlorination, and/or oxychlorination. The catalyst system comprises copper chloride impregnated onto an alumina support with a metal chloride selected from the group consisting of potassium chloride, lithium chloride, cesium chloride, magnesium chloride, calcium chloride or barium chloride, said alumina support having a sodium oxide content of from 0.2 to about 2.0% by weight and a silica content no more than 4%.
