Effect of Pore Structure of Al-Co-Mo Catalyst on Its Efficiency in Hydrodesulfurization of Black Oil

The effect of the volume of macropores (>100 nm) and pores 10-100 nm in radius in the Al-Co-Mn catalyst on its activity in hydrodesulfurization of black oil produced from West-Siberian oil was studied at varied process parameters.     

Effect of Pore Structure of Al-Co-Mo Catalyst on the Rate of Various Pathways of Hydrofining of Oil Residues

Evolution in the activity and texture of the Al-Co-Mo catalyst in hydrofining of black oil is studied. The catalyst efficiency in desulfurization, deasphalting, and demineralization of black oil is estimated as dependent on the catalyst pore structure and process conditions.     

Kinetics of Complexation of meso-Diphenyl-Substituted Alkylporphyrins with Zinc Acetate in Acetonitrile

Kinetics of interaction of diphenyl-substituted porphyrins and their derivatives with substituents in the phenyl fragments with zinc acetate in acetonitrile solution is studied. The effect of the solvent on the rate of coordination is shown. Kinetic parameters of complexation are calculated.     

On the Contributions of Feed Components to Hydrotreatment Catalyst Coking

The coking ability of some hydrocarbons (benzene, n-heptane, styrene, methylnaphthalene, durene, and phenanthrene) and heterocyclic compounds (thiophene and indole) under the conditions of hydrotreatment of feed is estimated for an Al–Co–Mo catalyst. The method of isotopic labels is used to determine the contributions of the components of binary mixtures to the formation of coke on the catalyst surface. These contributions do not coincide with the values of coking ability found for individual compounds.     

Effect of Composition of Al-Co-Mo Catalyst on Its Desulfurizing,Deasphalting, and Demineralizing Activity in Hydrofining of Oil Residues

Effect of the composition of Al-Co-Mo catalysts on their desulfurizing, deasphalting, and demineralizing activities in hydrofining of black oil and interrelation of these activities with coking and deactivation of the catalyst are studied.
