The article considers the effect of Al2O3 loading on the physical and chemical properties of cobalt catalysts. The loading of the alumina additive has a significant effect on both the phase and texture properties, as well as on the cobalt reduction process in the composition of the studied samples. It was found that with increasing loading of the additive, the specific surface area of the catalysts decreases, and the cobalt recovery process slows down.

The article presents the results of research on the morphology of cobalt catalysts for Fischer-Tropsch synthesis on a silicate support with promoting additives of aluminum, manganese and chromium using scanning and transmission electron microscopy. The effect of additives on the surface structure and dimensional characteristics of metallic cobalt was determined.

The article presents the results of research of the physical and chemical properties of cobalt catalysts on a zeolite support. Methods of BET, thermoprogrammed reduction, thermoprogrammed hydrogen desorption and IR-spectroscopy were used for study. The influence of the support nature on the structural (specific surface area, dispersion of metallic cobalt, size of metal crystallites) and chemical (degree of cobalt reduction) properties of catalysts was established.

The article presents the results of studies of cobalt catalysts for the synthesis of hydrocarbons on a silicate support with promoting additives of aluminum, manganese and chromium. The influence of additives on the structural (specific surface area, dispersion of metallic cobalt, size of metal crystallites) and chemical (cobalt reduction degree) properties of catalysts was established.
