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

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

Fischer-Tropsch Synthesis (FTS) using Fe-Co/meso-HZSM-5 catalyst has been investigated. The impregnated iron and cobalt on HZSM-5 could be used as bifunction catalyst which combined polimerizing synthesis gas and long hydrocarbon cracking for making biofu... see more

The analysis of the effect of cobalt concentration supported on mesoporous silica (MS) has been evaluated. This study was aimed to observe the physical and chemical characteristics of the catalysts, and also to study the catalytic activity and its selecti... see more

Partial oxidation of methane over mesoporous catalyst cobalt modified H-ZSM-5 has been carried out. Mesoporous Na-ZSM-5 (Si/Al = 35.4) was successfully synthesized using double template method which has high surface area (450 m2/g) and average pore diamet... see more

In order to investigate the phases of used Co/SiO2 catalysts, one of the most commonly used catalysts for Fischer-Tropsch synthesis, time-resolved X-ray absorption near edge structure (TR-XANES) technique was introduced. The catalysts were prepared by inc... see more

Based on the data of the thermoprogrammed desorption and using mass-spectroscopic analysis of desorbed products and on the kinetic patterns of the methanation process for cobalt–nickel catalysts, we suggested a mechanism for the reaction which passes thro... see more

In this article were given results of investigation the process of hydro treating the petrol fuel fraction from oil “Zhana zhol”. Catalytic properties of cobalt-humate and molibden-humate taken as catalysts for hydro treating process were investigated. It... see more

Pt-containing catalysts are currently used commercially to catalyze the conversion of carbon monoxide (CO) and hydrocarbon (HC) pollutants from stationary chemical and petroleum plants. It is well known that Pt-containing catalysts are expensive and have ... see more
