Silicoaluminophosphate (SAPO) zeolite SAPO-34 membranes with a uniform pore size of
0.38 nm and unique adsorption properties have been used in natural gas purification, H2 …

Abstract Silicoaluminophosphate-34 (SAPO-34) is a molecular sieve with a unique shape
structure and pore framework, favorable acidic properties, and excellent stability under …

It is desirable to develop high-performance composite membranes for efficient CO2
separation in CO2 capture process. Introduction of a highly permeable polydimethylsiloxane …

Abstract High-silica CHA (SSZ-13) zeolite membranes exhibit great potential for CO 2
separation. However, the practical application is significantly hindered by the high …

Due to their well-defined porosity, physical–chemical endurance, and catalytic property,
zeolite and zeotype membranes are becoming a more established choice for a broad …

A high silica CHA-type membrane was synthesized by the in-situ crystallization method on a
disk like α-alumina porous support to separate both acid (H 2 S, CO 2) gases from methane …

We demonstrate significantly enhanced conversion and selectivity in high-temperature
propane dehydrogenation (PDH) membrane reactors via the synthesis and use of small …

SAPO-34 membranes were synthesized in stainless steel autoclaves and teflon autoclaves
with water bath, ice/water bath and flowing water cooling towards N 2/CH 4 separation. The …

SAPO-34 zeolite membranes were activated by ultraviolet (UV) radiation at low
temperatures to reduce grain boundary defects. The successful detemplation of SAPO-34 …

Gas translation diffusion is proposed to compete with surface diffusion for describing the
permeation of light gases (He, H 2, CO 2 and CO) through zeolite membranes. The analysis …
