Natural zeolite membranes can be used as a model for the development of robust molecular sieve membranes with superior separation characteristics. We describe the characterization of natural clinoptilolite membranes made ...

Palladium composite membranes on porous stainless steel were prepared by electroless plating. In order to obtain a thin palladium film, an intermediate layer was necessary to modify the pore size of the substrate and form ...

NaA zeolite membranes were synthesized on top of both disk and tubular porous stainless steel substrates by the secondary growth method. The support seed stage was optimized, considering the seed synthesis conditions and ...

The permeation of a mixture of n-hexane, n-decane and toluene through a 40 μm Y zeolite tubular membrane on a support with negligible resistance to the mass transfer at 250 °C was modelled based on the Maxwell-Stefan ...

Mixed‐matrix membranes (MMMs) were prepared by combinations of two different kinds of porous fillers [metal‐organic frameworks (MOFs) HKUST‐1 and ZIF‐8, and zeolite silicalite‐1] and polysulfone. In the search for filler ...

PdAu composite membranes were applied for the preparation of PtNaA-PdAu catalytic membranes for hydrogen production from the water gas shift reaction. In the first stage, the deposition of NaA zeolite on top of the PdAu ...

The deposition of a NaA zeolite layer on porous stainless steel substrates was optimized in order to obtain composite membranes for hydrogen separation. The effect of the silica source on NaA zeolite crystallinity and ...

Disk membranes machined from high-purity natural clinoptilolite rocks demonstrated promising hydrogen separation efficiency. However, these membranes cannot be adequately scaled up. To overcome this and provide process ...
