What type of catalysts are used in industry?

Here are five common chemical catalysts used within the manufacturing industry.

  • Aluminosilicates. Aluminosilicates are a critical component of modern petrochemical manufacturing.
  • Iron. Iron has long been the preferred catalyst for ammonia production.
  • Vanadium.
  • Platinum + Alumina.
  • Nickel.

What is selective oxidation?

Selective oxidation of hydrocarbons is a very important industrial process that uses catalysts commonly based on transition metal oxides that are often vanadium and molybdenum oxides. For example, selective oxidation of hydrocarbons is usually carried out with oxygen or air.

What is selectivity in catalysis?

Catalysts are highly specific compounds. They have an ability to direct the reaction to yield a particular product. The reaction with same reactants but different catalyst may yield different products. This is termed as the selectivity of catalyst.

What are the industrial application of catalysts?

Catalysts speed up a chemical reaction by lowering the amount of energy you need to get one going. Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products. Catalysts are integral in making plastics and many other manufactured items.

How is selective oxidation used on an industrial scale?

Selective oxidation is one of the key reactions for the preparation of intermediates and fine chemicals. At an industrial scale, most of these reactions are still stoechiometric and lead to the formation of millions of tons of non recyclable and polluting by-products.

Why is selective oxidation important in a fuel cell?

Selective oxidation of CO in hydrogen-rich mixtures is an important reaction within the context of the fuel cell technology. The reactions have been operated in an excess oxygen gas in the temperature range of 150-200°C in order to provide efficient clean-up of hydrogen-rich stream from CO.

Is there a 100% selective oxidation of sulfoxides?

With the assistance of photoexcited Au 25 (SR) 18− at 532 nm irradiation, a ~ 100% selective catalytic oxidation of sulfides to sulfoxides was observed. The conversion increased with higher reaction temperatures or longer reaction times.

Which is a side reaction of selective oxidation?

The side reaction of sulfoxidation is the formation of sulfone. It is highly desirable to achieve selective oxidation of sulfides to sulfoxides under mild conditions.
