Catalyst compositions and process for oxychlorination

摘要

Oxychlorination catalyst compositions which include a catalytically effective amount of an oxychlorination catalyst and a diluent having certain chemical composition and/or physical properties are disclosed. Processes using such oxychlorination catalyst compositions are also described. Some oxychlorination catalyst compositions and processes disclosed herein can increase the optimal operating temperature, and thereby increase the production capacity of an existing reactor, such as a fluid-bed reactor, compared to other oxychlorination catalyst compositions.

1. An oxychlorination catalyst composition comprising:
(i) a catalytically effective amount of an oxychlorination catalyst comprising an active salt composition distributed on a support material; and (ii) a diluent comprising particles of a dehydroxylated, dehydrated or calcined alumina silicate having a surface area between about 1 m2/g and about 25 m2/g,wherein the support material and the diluent are different chemically, wherein the support material is selected from the group consisting of alumina, silica, magnesia, kieselguhr, fuller's earth, clays, porous rare earth halides and oxyhalides, and combinations thereof, wherein the surface area of the support material is between about 5 m2/g and about 450 m2/g, and wherein the diluent is catalytically and chemically inert.
