In this present study, the catalytic dehydration of ethanol over three different Al-based solid acid catalysts including H-beta zeolite (HBZ), modified H-beta zeolite with ?-Al2O3 (Al-HBZ) and mixed ?-? phase of Al2O3 (M-Al) catalysts was investigated. Th... see more

The catalytic ethanol dehydration to diethyl ether (DEE) over the synthesized beta zeolite (BEA) with different acidity on catalysts having Na and mixed Na-H forms was studied. The Na form of BEA catalyst was synthesized via the hydrothermal process, incl... see more

In this study, the polyethylene filled celluloses regarded as biocomposites was produced via in situ polymerization with zirconocene/MMAO catalyst. Three types of celluloses including microcrystalline cellulose (MCC), bacterial cellulose prepared from pin... see more

This study focuses on the production of acetaldehyde from ethanol by catalytic dehydrogenation using Co/C catalysts with different Co loading on the activated carbon derived from coffee ground residues. The simple impregnation was used to obtain the Co/C ... see more

Mesoporoustitania (TiO2) having high specific surface areas of 163 to 306 m2/g was prepared by a template-free one step reaction between TiC precursor and aqueous nitric acid (HNO3) solution. The effects of reaction parameters including acid concentration... see more

Effect of hydrogen and alkoxysilanes as external donor were investigated using two commercial Ziegler-Natta catalysts (TiCl4/MgCl2•nEtOH and TiCl4/phthalate type/MgCl2) in ethylene polymerization. These catalysts were analyzed by EDX, FTIR and XRD measure... see more

In the present work, the effects of Ti addition on the characteristics and catalytic properties of the different silica-based supported nickel (Ni) catalysts were investigated. The different supports, such as the spherical silica particle (SSP), MCM41, Ti... see more

The Co/SBA-15 and the Co/SBA-16 catalysts having 20 wt% of cobalt were prepared by the conventional impregnation method. Then, the post-impregnation treatments including vacuum and ultrasound treatments were applied. The synthesized catalysts were charact... see more

Ethylene/1-hexene copolymerization was performed over titania-supported zirconocene/dMMAO catalysts. Effects of titania having different phases on the catalytic activity and polymer properties were investigated. It was found that anatase titania exhibited... see more
