Application of Molybdenum in Petroleum and Chemical Industries

Molybdenum is a silver-white metal that has high hardness, high melting point, and high thermal conductivity. And it does not react with air at room temperature. Due to a variety of advantages, molybdenum and its compounds are widely used in the petroleum and chemical industries.

Petroleum cracking & reforming

Molybdenum plays an important role in petroleum cracking and reforming and is an ideal electron donor and carrier. Molybdenum has excellent acid and corrosion resistance and can be used to make vacuum equipment, heat exchangers, steamers, oil tank linings, various acid and alkali liquid containers, storage tanks and other chemical equipment materials. Molybdenum trioxide, molybdenum disulfide and organic molybdenum compounds are very important catalysts and catalytic activators in the petrochemical and chemical industries. They are commonly used in oxidation-reduction reactions, organic synthesis, petroleum hydro refining, ammonia synthesis, organic cracking, etc. In particular, molybdenum-containing catalysts have an important position in the petroleum processing industry.

Smoke suppressing

Molybdenum compounds, such as ammonium octamolybdate and calcium molybdate, are not only flame retardants but also smoke suppressing. If combined with inorganic and organic flame retardants, a synergistic effect can be achieved, and the effect of suppressing smoke is better.

Pigment industry

Some compounds of molybdenum are also widely used in the pigment industry. Lead molybdate, zinc molybdate and calcium molybdate are commonly used in the production of pigments, dyes, paints and inks.

Chemical reagents

Molybdenum compounds are also widely used as chemical reagents such as molybdenum trioxide, ammonium molybdate, ammonium paramolybdate, phosphomolybdic acid and sodium molybdate.


Molybdenum dioxide is a good solid lubricant. Its low coefficient of friction and high yield strength allows it to be used in vacuum and in either ultra-high or ultra-low temperature environments. Molybdenum dioxide lubricants are widely used in gas turbines, gears, abrasives and other fields.


Molybdenum compounds are one of the most widely used catalysts and are widely used in chemical, petroleum, plastic, textile and other industries. For example, molybdenum dioxide has anti-sulfur properties and can catalyze the hydrogenation of carbon monoxide to produce alcohols under certain conditions. It is a promising C1 chemical catalyst. Molybdenum is used in combination with cobalt and nickel as a catalyst for petroleum refining pretreatment. Other common molybdenum-containing catalysts are: molybdenum disulfide, molybdenum oxide, molybdate, etc.
