Use of graphite particles as diluent in a fixed bed exothermic reaction and process for the catalytic oxychlorination of ethylene.

摘要

Disclosed is a catalyst diluent which is made up of a graphite in a columnar shape having a diameter of between 3 and 6 mm and a height of between 3 and 6 mm. The cayalyst diluent produces the desired product in a high yield while preventing local overheating portion in a catalyst bed.
