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

Nano-TiO2 and its modification with gallium (nano-TiO2-Ga) and zirconium (nano-TiO2-Zr) were used here as nanofillers in production of linear low-density polyethylene (LLDPE). The nanoparticles were immobilized by modified-methyl aluminoxane (MMAO) to be ... 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

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 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

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

Different mesoporous titanias synthesized by hydrolysis and polycondensation reactions of tetrabutyl titanate with various hydrolysis ratios (H2O/Ti by mole) were employed as supports for zirconocene/MAO catalysts in ethylene/1-olefin copolymerization. Th... see more
