Description
A typical example of small-pore zeolites is the SSZ-39, which possesses a unique (AEI) topology and 8-membered ring (8-MR) channels. The Molecular Sieve SSZ-39 is a pure silicon-aluminum molecular sieve that overcomes the defect of poor hydrothermal stability of SAPO series molecular sieves and has good industrial application prospects. At present, the SSZ-39 molecular sieve is mainly applied to Methanol-to-Olefins (MTO) catalyst and Nitrogen Oxide (NO)x) Selective Catalytic Reduction (SCR) catalysts, and the like.SSZ-39 zeolite is considered the most promising for use in the field of catalysts due to its unique structure and high hydrothermal stability. SSZ-39 zeolite effectively acts as a support for the preparation of Ru catalysts in biomass conversion reactions, and it is possible to prepare highly active and hydrothermally stable catalysts for LA hydrogenation. In addition, they can be used for six consecutive cycles without losing any of their synthetic properties or catalytic activity[1].
