research topic
Deactivation behaviour of modified ZSM-5 zeolite catalysts to conversion of ethanol: mechanism, control and monitoring The aim of this project includes a systematic approach to improve long-term stability of an industrial zeolite of CLARIANT(R) by post-synthesis as well as a stepwise study of mechanism and structure-activity relationships during product formation and deactivation in Bio-ETH process.
