Zeolites are crystalline aluminosilicates containing pores and cavities of molecular
dimensions. Many occur as natural minerals, but it is the synthetic varieties which are among …

Zeolite catalysts and adsorbents have been an integral part of many commercial processes
and are projected to play a significant role in emerging technologies to address the …

There is a continuous worldwide interest in zeolite membranes. On the one hand side, we
can observe increasing numbers of scientific publications. On the other hand, there are first …

H-ZSM-5 crystals with various Si-to-Al ratios were coated with polycrystalline silicalite-1
layers by a repeated hydrothermal synthesis. The thus-formed silicalite-1 layers were …

Double-layered zeolitic imidazolate framework (ZIF) membranes were fabricated inside
polyimide P84 hollow fibers by a step-synthesis conducted by microfluidic technology and …

The diffusion of aromatics in pores has a great influence on the distribution of light aromatics
and the stability of zeolites, and the aromatics selectivity is related to the acidity of the …

Possible methods for the preparation of colloidal zeolite sols are discussed: direct synthesis
is at present the only practicable procedure. The linear crystal growth rate for colloidal TS-1 …

Polycrystalline silicalite layers were formed on H-ZSM-5 with different crystal sizes of 5–
30μm. The silicalite-1/H-ZSM-5 composite with a crystal size of 5μm showed high catalytic …

Nanostructure ZSM-5 zeolite was synthesised via hydrothermal, chelating agent-based
method from a mixture with molar composition of 1Al2O3: 46SiO2: xTPA: 5Na2O: 1.3 Trien …

The introduction of industrial membrane-based separation technologies can dramatically
reduce the separation costs in comparison with thermally based separation technologies. In …
