Difficulties in the industrial introduction of new effective hydrodesulfurization catalysts in the Russian Federation
Department of Chemical Technology and Processing of Utilities, Faculty of Raw Material Processing, St. Petersburg Mining University, Russia
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.
