Enhancing Syngas Conversion Selectivity with Dynamic Confinement in OXZEO Composite Catalysts

Scientists from the Dalian Institute of Chemical Physics(DICP)of the Chinese Academy of Sciences have reported for the first time the induction period in syngas conversion over an OXZEO composite catalyst,ZnCrOx-SAPO-17.During this period,a dynamic confinement develops within the SAPO-17 cage,which enhances the selectivity of ethylene and suppresses that of C4+hydrocarbons.
