Molybdenum is a ⅥB element metal is a transition metal. 

 

Molybdenum elements N, O two electron shell is incomplete, the element is given both electrons and accept electrons is very easy, so that the valence of molybdenum can take place under stable conditions change, the molybdenum can be a divalent, trivalent, tetravalent, pentavalent and hexavalent. Variability valence of molybdenum, molybdenum has excellent catalytic performance. 

 

As we all know, tens of thousands of chemical reactions, of which 80% need the help of various types of catalysts can be carried out smoothly. 

 

Molybdenum-based catalysts varied, the application is very broad, prominent position in the catalyst is particularly important especially in the petrochemical industry and chemical industry. 

 

Molybdenum-based catalysts are widely used in petroleum hydrotreating, hydrodesulfurization, hydrodenitrogenation, propane, isobutane ammoxidation of acrylonitrile and methacrylonitrile, or acrylic acid and crotonic acid preparation, oxidation of butane to maleic anhydride (CHCO2) 2O; 1- butene oxidative dehydrogenation of 1,3-butadiene to produce ethanol from synthesis gas, or mixture of C1 ~ C4 alcohol. Catalytic pyrolysis of carbonaceous gas source production of carbon fiber or single-wall carbon nanotubes. Production of synthesis gas reforming and fuel cells. Lignite liquefaction, purification of exhaust gas containing NOX gas phase oxidation of acrolein and the production of acrylic acid and the like. 

 

Application of molybdenum-based catalysts from spent catalyst and regeneration and recovery of valuable metals are typically circular economy. Catalyst is a low-carbon industry, green technology. According to statistics, from 2000 to 2009, the annual consumption of molybdenum molybdenum catalyst of about 17,000 ~ 18,000 t, accounting for about 7% of the total consumption of molybdenum, in 2009 the global recovery from the spent catalyst molybdenum approximately 16,000 t. 

 

With the global economic recovery and growth, oil consumption will continue to grow, is expected in the foreseeable future, at least molybdenum catalyst annual growth of more than 8%.
