Gas membrane separation technology is a kind of mixed gas with low energy consumption, simple equipment, easy operation and no influence on the environment. Due to special properties graphene oxide (GO) membrane, GO has become research hotspot technology. In this paper, A critical thickness demonstrated: when less than 600nm, conductance inversely exponential thickness, but proportional thicker...

Separation and capture of carbon dioxide (CO2) has become a very hot topic discussion recently. The increasing amount in the environment makes environmental pollution significant. Membrane technology is one alternative separation processes that are increasingly demand, because membrane provides excellent advantages terms energy requirements used, capital investment invested, ease operating equi...

the current study presents synthesis and characterization of high impact polystyrene - tio2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. the solution-casting method was used for preparation of membranes. the nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...

Membrane separation technology is widely explored for various applications, such as water desalination and wastewater treatment, which can alleviate the global issue of fresh water scarcity. Specifically, carbon nanotubes (CNTs)-based composite membranes are increasingly of interest due to the combined merits of CNTs and membrane separation, offering enhanced membrane properties. This article f...

The most effective include absorption, adsorption, cryogenic distillation, chemical looping combustion, membrane separation. study over 100 published studies assess their characteristics, benefits, drawbacks. choice of technology ...

The performance of an optimized tree-type cylindrical-shaped nanoporous fltering membrane proposed in the former study is analytically investigated for varying operational parameter values. Across the membrane thickness, this membrane has two-leveled tree-structured pores including one trunk pore and the multiple branch pores. The physical properties of the surfaces of ...

the main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. the synthesized membranes were characterized by x-ray diffraction (xrd) and scanning ...

Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...
