Investigation of Small‐Pore Zeolites Via Vapor‐Phase Adsorption of N‐hexane
Chemie-Ingenieur-Technik/Chemieingenieurtechnik(2021)
摘要
Cage-based small-pore zeolites are promising catalysts for catalytic applications such as methanol-to-olefins to produce light olefins and selective catalytic reduction to mitigate NOx emissions. The present paper reports our recent studies on vapor-phase adsorption of n-hexane in a series of small-pore zeolites with cages such as 3A, 4A, 5A, ITQ-29, SSZ-13, SSZ-16, SSZ-17, SSZ-36, SSZ-50, ITQ-12, ZK-5, and Rho. The effects of zeolite compositions and crystal sizes on the adsorption kinetics and capacity are investigated, demonstrating that n-hexane adsorption is a useful tool for characterizing the effective pore sizes and volumes of small pore zeolites.
