PURPOSE: Provided is an excellent catalyst for fixed bed oxychlorination method, which 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 process. CONSTITUTION: This cylindrical hollow moulded catalyst comprises a carrier and a catalytically active material consisting of copper carried on it. The copper is present on the dried catalyst and the content of the copper is 1-12 weight%. The catalyst is formed in a hollow cylinder shape to have dimensions, 4.0 <= De <= 7.0, 2.0 <= Di <= 2.8, 6.1 <= L <= 6.9, and 2.0 <= Do/Di <= 2.5, wherein De is the external diameter (mm) of the hollow cylinder; Di is the internal diameter (mm) thereof; and L is the length (mm) thereof.
