“…For water/alcohol pervaporation across CHA zeolite membrane, the experimental data of Hasegawa et al [79] show that the alcohol fluxes decrease with increasing water composition in the feed. Indeed, both water and alcohol fluxes are reduced with increasing concentrations of partner species in the mixture.…”

“…Zeolite membranes are considered to be the most promising candidates for pervaporation (PV) [1][2][3][4][5][6][7] and gas separation [8][9][10] because of the unique characteristics of zeolite crystals such as well-defined pore structures, selective adsorption, and high thermal stability. Zeolite NaA membranes with the excellent PV performance have been successfully applied for dehydration of some organic solvents on a large scale [1].…”

“…Chabazite (CHA framework) owns similar pore properties (3-dimeteral and interconnected small pores and relative low framework identity), but an increased crystal Si/Al ratio (2)(3)(4)(5) compared with zeolite NaA (LTA framework). The 8-ring channels have a pore size of 0.38 nm which is smaller than most alcohols but larger than water.…”
“…However, the mechanical strength of the CHF support with 75 wt% zeolite crystals is increased at the expense of its porosity [7]. The influencing factors of the separation performance of zeolite membranes have been extensively investigated [7,[9][10][11][12][13][14][15][16][17][18][19]. It is found that the pervaporation flux of zeolite membranes increases with the porosity of the supports [6].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
