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

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

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

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

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

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

Born in southern California in 1919, James Plummer Morgan would emerge from training at Berkeley and Louisiana State University to make several profound contributions in the disciplines of deltaic geology and coastal geomorphology. As an indirect, academi... 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
