An integrated approach to the key parameters in methanol-to-olefins reaction catalyzed by MFI/MEL zeolite materials

Identification of the catalyst characteristics correlating with key performance parameters including selectivity and stability is to rational design. Herein we focused on identification property-performance relationships in methanol-to-olefin (MTO) process by studying detail catalytic behaviour MFI, MEL their respective intergrowth zeolites. The detailed material characterization reveals that both high production propylene butylenes large MeOH conversion capacity correlate enrichment lattice Al sites channels pentasil structure as identified 27Al MAS NMR 3-methylpentane cracking results. lack correlation between MTO other characteristics, such crystal size, presence external Brønsted acid pairing suggests less pronounced role defining selectivity. Our analysis deactivation rather complex strongly affected intersections, overall Al-content, size. MFI phases accelerates rate.
