Abstract The membrane support is the basis for preparation and application of zeolite its cost properties directly determine performance as well industrial applications. In this paper, direct synthesis NaA on a novel low-cost via an in situ reaction by utilizing natural clay can enable significant reduction manufacturing costs. During membrane, additives, such Al 2 O 3 , Al(OH) AlF were combine...

Five alkali-activated analcime (ANA) sorbents (ANA-MK 1, ANA 2, 3, ANA-MK 4, and 5) were developed for ammonium (NH4+) ion removal. Acid treatment calcination used as pre-treatments analcime, metakaolin (MK) was a blending agent in three sorbents. Sorption experiments performed to evaluate the effects of sorbent dosage (1–20 g L−1), initial NH4+ concentration (5–1000 contact time (1 min–24 h). ...

GIS-NaP1 zeolite samples were synthesized using seven different Si/Al ratios (5-11) of the hydrothermal reaction mixtures having chemical composition Al2O3:xSiO2:14Na2O:840H2O to study the impact of Si/Al molar ratio on the water vapour adsorption potential, phase purity, morphology and crystal size of as-synthesized GIS-NaP1 zeolite crystals. The X-ray diffraction (XRD) observations reveal tha...

This review provides a fundamental assessment of the potential zeolite particles incorporated into polymeric membranes in view improving performance these membranes. Zeolites are interest as having extensive separation processes due to their unique frameworks and properties. Significant investigations have been carried out improve conventional membrane properties by inclusion zeolites. Zeolite ...

Microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-Al2O3 supports at two different synthesis conditions (i.e. two different routes). Microstructures of the synthesized membranes were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and si...

The increasing use of motor vehicles, the greater amount engine oil consumption. Engine cannot be used continuously due to frictional force on engine, so is purified. Unused can pollute environment because it categorized as B3 waste. Used has a higher metal content than new oil. reduction in done by using filtration column containing zeolite and activated carbon with height 20 cm from each medi...

Ethanol / Water Separation Technology is a long-term research. LTA molecular sieve, which an industrially important desiccant as kind of zeolite sieve. It always used in the reverse osmosis method, one seawater ddesalination, and extraction industrial ethanol method world. Membrane separation technology widely cell science, human microbial military industry, battery so on. With 2 years inventio...
