Abstract
CoMo sulfide catalysts supported on an MCM-41-type ordered mesoporous silica and on a hierarchical aluminosilicate material based on halloysite nanotubes (MCM-41@HNT) were synthesized by incipient wetness impregnation. Both the supports and related catalysts were characterized by low-temperature nitrogen adsorption–desorption, energy dispersive X-ray fluorescence analysis, FTIR spectroscopy of adsorbed pyridine, transmission electron microscopy, and X-ray photoelectron spectroscopy. The catalyst samples were further tested in hydrodesulfurization of 4,6-dimethyldibenzothiophene. The MCM-41@HNT-supported catalyst exhibited the greatest activity in the main reaction (hydrodesulfurization) due to its hierarchical porous structure and the presence of high-temperature Brønsted acid sites.
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
