ABSTRACT:
The present invention provides a fixed bed catalyst for the oxychlorination of ethene, alpha olefins and aromatics. More specifically, this invention relates to a catalyst having an impeded center which excludes reactants, or prevents products from forming in the interior of the catalyst. The impeded center may be made inaccessible or it may be inert to reaction. Thin layers of high specific surface area carrier material cover the outer surface of the impeded center. An agent capable of catalyzing oxychlorination reactions is added to the layered catalytic carrier material.
