Catalytic dechlorination of chloroorganic compounds from PVC-containing mixed plastic-derived oil

The dechlorination of chloroorganic compounds from PVC-containing mixed pla stic-derived oil was studied over iron oxide and iron oxide-carbon composit e catalysts. The catalysts are characterised by nitrogen adsorption and X-r ay diffraction. The catalysts are deactivated initially due to the adsorpti on of HCl gas that is produced during the reaction. Continuous adsorption o f HCl on iron oxide leads to the conversion of iron oxide to iron chloride. The catalysts' deactivation was overcome by removing the reversible adsorb ed HCl gas continuously, using He as a carrier gas. (C) 2001 Elsevier Scien ce B.V. All rights reserved.
