Porous inorganic membranes are usually composed of several layers, which are asymmetric with respect to the flow direction. For permanent gases, investigations about the influence of the flow direction on the mass flux through an asymmetric ceramic m

A new CMS membrane with smaller gas pair H2/CO2 and H2/CH4 separation factor of approximately 8.3 and 726, with an H2 permeability of 600.7 Barrer, was synthesized by coating it on titanium gel-modified alumina supports. After calcination, the titani

The transport of carbon dioxide and methane through the liquid film of the bubble is studied. The liquid film is formed by blowing into a solution containing surfactants, sugar, glycerol and around 60% of weight of water, leading to formation of a bu

The selectivity and permeability of membrane material determines the efficiency of the gas separation process. To prepare a stable high selective and high permeable membrane and, in addition, also cheap, is the dream of most scientists dealing with t

A novel simple and efficient procedure for the study of binary mixtures pervaporation transport through polymer membranes is reported. The basic idea is a gradual increase of one component concentration in the feed mixture instead of time-consuming r

New composite membrane with a poly(γ-benzyl- l -glutamate) (PBG) separation layer on a micro-porous poly(amide-imide) support was prepared and tested as a pervaporation membrane for selective separation of toluene/ n -heptane mixtures. Composite mem

A robust procedure to estimate vapor diffusion coefficients from unsteady state measurements is proposed. The permeate flux is measured for a step change in the inlet. The method is based on the interpretation of the normalized permeate flux over tim

We present experimental data of the flow of butane and isobutane vapors through porous Vycor glass membranes. The pressure driven flow of vapors near and far from saturation through membranes with pore diameters of 20 and 33 nm is investigated. The u
