Catalyst and catalytic oxychlorination process in which this catalyst is employed

摘要

A cylindrical hollow moulded catalyst having a size of 4.0-7.0 mm in outer diameter, 2.0-2-8 mm in inner diameter, 6.1-6-9 mm in length and with the ratio of its outer diameter to its inner diameter in the range 2.0 to 2.5. The moulded catalyst has a low resistance to flow, allows good heat exchange with the wall of the industrial reactor, has good effectiveness and, with a suitable active phase based on copper and such additives as alkali and/or alkaline earth metals and/or lanthanides, produces a good catalyst for fixed bed oxychlorination processes.
