Platinum catalyst

Platinum catalyst, also known as platinum catalyst, is a general term for catalysts made primarily from platinum metal as the active component. The following is a detailed introduction about platinum catalysts:

1. Composition and preparation

• Main components: Using platinum as the main active component, it may also contain co catalyst components such as rhenium metal.

• carrier: Platinum metal mesh, platinum black, or platinum loaded on carriers such as alumina.

• Preparation method: including hydrothermal method, precipitation coprecipitation method, sol gel method and atomic layer deposition method. These methods each have their own characteristics, for example, hydrothermal method has relatively low cost but longer reaction time, while atomic layer deposition method has high accuracy but also higher cost.

2. Application Fields

• Platinum catalysts are widely used in chemical, petroleum, and chemical reaction processes, such as ammonia oxidation, petroleum hydrocarbon reforming, unsaturated compound oxidation and hydrogenation, and removal of carbon monoxide and nitrogen oxides from gases.

• It can be used as catalyst for liquid addition silicone rubber, silicone gel, addition compound, electronic potting adhesive, silicone ink, etc., as well as catalyst for synthesis of polyether silicone oil, amino silicone oil, etc.

• In the petroleum refining industry, platinum catalysts are used in the platinum reforming process to remove C6 from petroleumConversion of C8 alkane fraction to C6The process of C8 aromatic hydrocarbons, namely benzene, toluene, and xylene.

3. Characteristics and advantages

• High catalytic activity: Platinum catalysts have high catalytic activity and can effectively promote chemical reactions.

• Strong selectivity: Has high selectivity for specific chemical reactions and can optimize the composition of products.

• Easy to produce: The production process of catalysts is relatively simple and easy to achieve industrial production.

• Low usage: Due to its high catalytic activity, the required amount of catalyst is relatively small.

• Can optimize performance: By changing and improving manufacturing methods, and compounding with other metals or active components of co catalysts, catalytic performance can be optimized.

• Reusable：Platinum catalysts have a long service life and can be repeatedly regenerated and activated for use.

• Environmental friendliness：The metal palladium from waste catalysts can be recycled and reused, which meets environmental protection requirements.

4. Typical physical properties

• Platinum (Pt) element is located in Group 10 (VIII B) of the periodic table, with an atomic number of 78. It has a silver white appearance and good ductility.

• Density 21.45g/cm ³, melting point 1769 ℃, boiling point 3827 ± 100 ℃.

5. Future Development

Platinum catalysts still have great development prospects. With the advancement of technology, platinum catalysts with new structures and catalytic functions are still being developed, which is expected to make more difficult to achieve reaction processes possible and improve the efficiency and economic benefits of industrial production such as petroleum and chemical industry.
