A comprehensive review on sustainability-motivated applications of SAPO-34 molecular sieve

Thermocatalytic CO2conversion by siliceous matter: a review

“…194 By performing identical dissolution–regrowth processes together with the involvement of a structure-directing agent, other classes of porous catalysts or substrates such as zeolites can be obtained. 195 Precipitation, encapsulation, self-assembly, co-assembly, infusion, immobilization–encapsulation, and deposition–precipitation are commonly employed for loading or embedding various active phase metals during or after the synthesis stage of siliceous materials. 193…”

“…Therefore, zeolite-based catalysts, a subsidiary of silica-derived materials, have been proven to be useful in a wide range of applications. Specifically, the major clean catalytic applications for zeolites include Friedel–Crafts, 272 Beckmann rearrangement, 273 Fischer–Tropsch (FT), 274 hydroconversion, 275 oxidation reactions, 276 catalytic cracking, 277 methanol-to-olefin (MTO), 195,278 and biomass conversion. 279 Besides, the applicability of zeolites has also demonstrated for other important environmental applications such as CO 2 capture and wastewater treatment.…”

Recent Progress of SAPO-34 Zeolite Membranes for CO2 Separation: A Review

“…Furthermore, state-of-the-art SAPO-34 membranes and membranes reactor were addressed by Xu et al [ 55 ]. Rimaz et al proposed SAPO-34 as a best molecular sieve [ 56 ]. Kumar et al studied CO 2 capture by different zeolites in general, whereas Singh et al [ 39 ] explored porous materials for CO 2 capture applications.…”

Zeolite-based catalytic membrane reactors for thermo-catalytic conversion of CO2

“…In terms of CO 2 utilizations, two representative reactions are mostly studied using zeolite-based catalytic membrane reactors, that is, CO 2 hydrogenation ( Raso et al., 2021 ; Tavolaro and Tavolaro, 2017; Gorbe et al., 2018 ) and dry reforming of methane (DRM) ( Bosko et al., 2010 ). In the last few years, however, relevant reviews are only focused on the following topics: zeolite catalysts for VOC removal ( Feng et al., 2018 ), developments of specific zeolite structures ( Rimaz et al., 2022 ; Collins et al., 2020 ; Li et al., 2021c ; Xu et al., 2021 ) and zeolites membranes adopted in heterogeneous reactions ( Wenten et al., 2021 ). Therefore, this review for the first time discusses the applications of zeolite membrane reactors in the CO 2 adsorption, separation, activation, and conversion in reforming and hydrogenation processes, together with the impacts of operation conditions.…”
