Abstract

The monograph presents results of studies of some selected problems relating to CoMo-Al{sub 2}O{sub 3} catalyst: method of production alumina support and catalyst; application of catalyst in the selected hydro refining processes; physicochemical properties of the used catalyst; reclamation of metal compounds from the spent catalyst. Results of investigations of catalyst preparation illustrate how the physicochemical properties of alumina support and catalyst, mainly porous structure could be controlled by the selection of raw materials and parameters of aluminum hydroxide precipitation, method of forming and calcination temperature of support. Application of the catalyst of modified porous structure has shown its high activity in hydro refining process of light cracking catalytic oil (over 95% hydrodesulphurization) and mild hydro cracking process of vacuum gas oil (sulphur content in product below 0.03% wt.). As an effect of studying of hydro refining process of aromatic hydrocarbon fraction it has been found that H{sub 2}S concentration in reaction mixture is the main factor influencing process selectivity. Some effect on the selectivity exerts also other process parameters and chemical composition of the catalyst - cobalt molybdenum content ratio and promoters content. Long term exploitation of the domestic CoMo-Al{sub 2}O{sub 3} catalyst in hydrodesulphurization process indicates its satisfied  More>>

Long term exploitation of the domestic CoMo-Al{sub 2}O{sub 3} catalyst in hydrodesulphurization process indicates its satisfied thermal stability although results in deteriorating of mechanical resistance, lowering of specific surface area, increase in mean pore radius and decrease in acidity of catalyst. In the last chapter of the monograph the results of investigations of reclamation of metal compounds (molybdic acid, aluminum hydroxide, cobalt carbonate) from the spent catalyst as well as an original technology of manufacture of the fresh one using these compounds have been presented.
