Modifying of HY/Zeolite is by loading nickel for applying catalyst in thermal catalytic cracking furfural extract-40 from the lubricating base oil unit. The study involved characterizing HY-zeolite and promoted with X-ray diffraction analysis, Scanning electron microscopy (SEM), BET (Brunauer, Emmett, Teller), infrared ray analyses FTIR. tubular reactor a fixed bed two type catalysts; HY/zeolit...

Zeolite 4A, synthetic silicate, has been shown to exhibit diverse biological activities such as anti-cancer and anti-oxidant activity. In the present study, we report that the zeolite 4A may improve skin-whitening. We found that zeolite 4A inhibited melanin production in a dose-dependent manner, which has not cytotoxicity. Zeolite 4A also inhibited alpha-melanocyte-stimulating hormone (alpha-MS...

Temperature-dependent zeolite synthesis has revealed a unique surface morphology, surface area and pore size which influence the immobilization of urease on gold electrode supports for biosensor fabrication. XRD characterization has identified zeolite X (Na) at all crystallization temperatures tested. However, N₂ adsorption and desorption results showed a pore size and pore volume of zeolite X ...

The synthesis of NaY-zeolite was performed hydrothermally. preparation the bifunctional catalysts achieved by loading NH4Y-zeolite with a cheap Zr metal, as second tiny amounts Pt to compose Pt-Zr/Y-zeolite catalyst. Different characterization methods (i.e., XRD, SEM, EDX, BET, and AFM) were used investigate catalyst properties. catalytic performance studied performing hydroisomerization n-hept...

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 microwave technique. in thi...

The photodecomposition products of Ru(bpy)3(2+) in water, in aqueous buffered solutions and encapsulated in zeolite-Y have been analyzed by chromatography and UV-visible spectroscopy. The chromatographic method is found to be capable of separating species with the same charge but slightly different ligands as well as geometrical isomers. In all the systems investigated, photodecomposition proce...
