Abstract
Highly active, improved ethylene oxychlorination catalysts are prepared by forming alumina having specific pore volume characteristics and impregnating such alumina with an oxychlorination catalyst such as CuCl.sub.2. The improved catalysts of the present invention utilize an alumina carrier having a pore volume distribution such that substantially no pores are present which have diameters of less than 150 .ANG.ngstroms and the total alumina carrier has a surface area of at least 30 square meters per gram.
