Recirculation and Regeneration of Molybdenum-Containing Ultradispersed Catalysts in the Hydroconversion Processes of Carbon-Containing Raw Materials: A Review

Resumo

It was shown that hydroconversion processes with the use of ultradispersed molybdenum-containing catalysts are promising lines in the production of motor fuels from different forms of organic raw materials. Molybdenum disulfide is the catalytically active form regardless of the method of introduction and the composition of precursors used. This fact makes it possible to develop the general principles of the extraction of molybdenum compounds from the residues of the hydroconversion of organic raw materials. The known data on methods used for the extraction and regeneration of Mo-containing compounds in the hydrotreating of heavy charges and from molybdenite-containing minerals were generalized.
