Abstract

A commercial pyrolysis process of ethylene dichloride (EDC) into vinyl chloride monomer (VCM) revealed two types of carbons produced, a pyrolytic carbon deposited on the reactor tube wall and the carbonaceous grains deposited from feed EDC on the external wall of the tube in the heat exchanger. An isotropic carbon produced on the wall side of the tube in the heat exchanger was characterized in terms of its morphology, optical texture and graphitizability. The isotropic carbon was carbonized under Ar flow and observed by a polarized light optical microscope and scanning electron microscope equipped with energy dispersive X ray analysis. The analyses of the surface compositions of the as-produced carbon are summarized.
