Abstract
The present invention provides a cylindrical hollow moulded catalyst having an outer diameter ranging from about 4 mm to about 7 mm, an inner diameter ranging from about 2 mm to about 2.8 mm, length ranging from about 6.1 mm to about 6.9 mm, and the ratio of the outer diameter to the inner diameter ranging from about 2 to about 2.5. The molded catalyst of the present invention is effective in the oxychlorination process, has a low resistance to flow, allows for good heat exchange with the wall of an industrial reactor and, with a suitable active phase based on copper and such additives as alkali metals, alkaline earth metals, group IIIB metals and lanthanides, is a good catalyst for fixed bed oxychlorination processes.
