Microwave Assisted Synthesis of Nano Zeolite Seed for Synthesis Membrane and Investigation of its Permeation Properties for H2 Separation
MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with m...
متن کاملDensity Functional Theory Study of Silica Zeolite Structures: Stabilities and Mechanical Properties of SOD, LTA, CHA, MOR, and MFI
We have investigated various silica zeolites using density functional theory with periodic supercells, plane waves, and pseudopotentials. These zeolitic phases include silica sodalite, chabazite, mordenite, silica LTA, and silicalite. Atom-level geometries, elastic properties, and cohesive energies are presented. Although the zeolites exhibit a wide range of Si-O-Si angles and densities, the co...
متن کاملSynthesis and characterization of optically active polyester thin-film bionanocomposite membrane achieved by functionalized cellulose /silica for gas permeation
Optically active bionanocomposite membranes composed of polyester(PE) and cellulose /silica bionanocomposite (BNCs) are a novel method to enhance gas separation performance. Commercially available silica nanoparticles were modified with biodegradable nanocellulose through ultrasonic irradiation technique. Transmission electron microscopy (TEM) analyses showed that the cellulose/silica composite...
