The commercial SAPO-34 zeolite with 0.38 nm pore size and ZIF-8 particles 0.34 aperture were separately dispersed into different polymer matrix, to prepare the mixed matrix membranes (MMMs) for gas separation. situation of in influence fillers on separation performance membrane had been investigated this study. as-synthesized MMMs showed a better trade-off between permeability selectivity than ...

BACKGROUND Butanol is regarded as an advanced biofuel that can be derived from renewable biomass. However, the main challenge for microbial butanol production is low butanol titer, yield and productivity, leading to intensive energy consumption in product recovery. Various alternative separation technologies such as extraction, adsorption and gas stripping, etc., could be integrated with aceton...

Membrane gas separation at high temperatures and in the presence of aggressive chemicals, such as H2S, NH3, SOx, NOx hot water vapor, is attracting interest from both a fundamental industrial standpoint. To fully exploit benefits membrane technology, it imperative to develop materials that withstand thermally chemically harsh conditions, well understand principles underpinning transport species...

Commercialized silicoaluminophosphate-34 (SAPO-34) zeolite was successfully blended in the polyethersulfone (PES) polymer to prepare mixed matrix membranes (MMMs). The CO2 permeability and CO2/CH4 ideal selectivity of 30 wt% SAPO-34/PES MMM at 0.1 MPa 35 °C were 15 barrer 51, respectively. In our previous paper, PES MMMs using laboratory-made SAPO-34 provided both higher than neat membrane. per...
