Noblyst® E 39 Khl - High Performance Catalyst For Improved Process Efficiency

Monday, August 22, 2005 by Evonik Degussa

Vision

• Reduced by-product formation in the VCM production process Competence / Technical Approach

• Implementation of selective hydrogenation step to convert acetylene in process HCl-recycle stream

• Catalyst with optimized performance which works at high space velocity

• Minimized precious metal content as active material

Benefits

• Improved selectivity of the oxychlorination process

• Higher EDC purity, minimum by-product yield of undesirable chlorinated hydrocarbons

• Lower cost for by-products separation and management

• Lower fouling rates for the EDC cracking furnace

• Lower investment for hydrogenation catalyst

• High recovery rate for the precious metal from the spent catalyst

Roadmap

• Promote the implemation of the optimized catalyst for selective hydrogenation in VCM plants
