MONOLITH STRUCTURE LOADED WITH METAL PROMOTED NANOZEOLITES FOR ENHANCED PROPYLENE SELECTIVITY IN METHANOL CONVERSION

摘要

A catalyst system and a process for methanol to light olefin conversion with enhanced selectivity towards propylene. The catalyst system comprises a honeycomb monolith catalyst support coated with nanozeolite catalysts on the edges and inside the channels of the support structure. The nanozeolite catalysts have been pre-modified with metal. The catalyst system gives higher hydrothermal stability to the catalyst compared to randomly packed pellet catalyst and allows methanol to be converted to predominantly propylene at a low temperature, with decreased selectivity towards C2, higher olefins and paraffinic hydrocarbons.
