Noblyst® E 39 Khl - High Performance Catalyst For Improved Process Efficiency
22 August 2005
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
