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

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

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

In this present study, the zirconia-modified different crystallite sizes of TiO2 (11, 13 and 16 nm) as support for the cobalt catalysts were investigated. The different TiO2 crystallites derived from the sol-gel method was obtained by varying the water:al... see more

In the present study, different cobalt precursors, such as cobalt acetylacetonate (CoAA), cobalt acetate (CoAC), cobalt nitrate (CoN) and cobalt chloride (CoCL), were employed to synthesize the cobalt on cobalt-aluminate catalysts by the solvothermal proc... see more

The two different kinds of impregnation (in situ and ex situ were used in the heterogeneous copolymerization of ethylene and 1-hexene for production of LLDPE/silica composite. For the ex situ impregnation, MMAO cocatalyst was immobilized firmly onto the s... see more



The performances of MgO admixed WO3/SiO2 catalysts were investigated in the cross metathesis of ethylene and 2-butene to propylene at 450oC atmospheric pressure. Compared to the WO3/SiO2 + silica gel, the conversion of 2-butene and the propylene selectivi... see more
