Difficulties in the industrial introduction of new effective hydrodesulfurization catalysts in the Russian Federation

The article presents bibliographic knowledgeof the world-scaleinventions that formed the basis ofHDS-catalysts for the development of variousoil products. Extensive studies were conductedon optimizationof carrier properties, active-phase chemical-mass composition, and basictech-nological parameters of transformation of initial components into active six-sided MoS2 groups which are decorated by CoS2 molecules, involving stages of desulfurization ofoxide formsof the catalyst. Differences in the microstructure of Al2O3supportsderived from aluminum hydroxide of vari-ous genesis are described. Comparative possibilitiesof binding properties of aluminum hydroxide raw materials in laboratory tests and molding of-waterpeptidized pastesare presented.
