摘要: One dimensional pore zeolites such as ZSM-22 (TON) are potential catalysts for hydrocarbon conversion reactions, including methanol-to-propylene (MTP) reaction. Different crystal lengths of zeolite were prepared and examined the MTP Nanosized TON with length ∼100 nm synthesized by dynamic hydrothermal synthesis. The was tuned using ethylene glycol growth modifier. (approximately 100 300 nm) confirmed from FE-SEM TEM micrographs. However, textural properties BET surface area crystallinity crystals fairly similar. effect on catalytic activity propylene yields in reaction investigated. nanocrystals resulted a higher yield better stability compared to submicrometer (∼300 nm). Deactivation observed all catalysts. longer lifetime ...
