Abstract
Oxychlorination of ethylene is carried out using a three-reactor system containing beds of a catalyst comprising a spherical, high-surface area activated alumina impregnated with cupric chloride and potassium chloride. In the first two reactors, the catalyst bed is divided into two sections, with a more active catalyst in the lower section than in the upper. The catalyst is substantially undiluted with inert particles. A new catalyst for such a process is also provided.
