Catalysts play an important role in the field of raw materials for chemical production, and their upstream and downstream related products are extensive. This article will discuss in detail the upstream and downstream related products of the catalyst, including upstream raw materials, downstream applications and related chemical products.

1. Catalyst Upstream Feedstock The upstream feedstock of the

catalyst mainly includes metals, non-metals and some compounds. These raw materials are processed by a specific process to prepare a catalyst with catalytic activity. The following are some common catalyst upstream raw materials:

1. Metal raw materials: The metal raw materials commonly used in catalysts include precious metals such as platinum, palladium, rhodium, and ruthenium, and non-precious metals such as copper, nickel, iron, and cobalt. These metals act as active components in the catalyst and can promote the progress of chemical reactions.
2. Non-metallic raw materials: Non-metallic raw materials such as oxygen, nitrogen, carbon, etc., are also commonly used in the preparation of catalysts. These non-metallic elements can form oxides, nitrides and other compounds, as a catalyst carrier or active component.
3. Compound Raw Materials: Some compounds such as acid salts, complexes, etc. can also be used as raw materials for catalysts. These compounds form catalytically active substances by chemical reaction during the preparation of the catalyst.

2. catalyst downstream application field

catalyst is widely used in the field of chemical production raw materials, involving many fields. The following are some common downstream applications of catalysts:

1. Petrochemical: In the petrochemical field, catalysts are widely used in cracking, hydrogenation, dehydrogenation and other reaction processes. In these reaction processes, the catalyst can improve the reaction rate and selectivity, and improve the quality and yield of the product.
2. Environmental protection: Catalyst has a wide range of applications in the field of environmental protection, such as automobile exhaust gas treatment, industrial waste gas treatment, etc. The catalyst can promote the conversion and decomposition of harmful gases, reduce pollutant emissions and protect the environment.
3. New energy field: In the field of new energy, catalysts are often used in the manufacture of fuel cells, photovoltaic cells and other equipment. Catalysts can improve energy conversion efficiency and stability, and promote the development of new energy industry.

3. catalyst related chemical products

catalyst production and use process, involving many related chemical products. The following are some chemical products related to the catalyst:

1. Carrier: The carrier is an important part of the catalyst, which can support and disperse the active components. Common support materials include alumina, silica gel, activated carbon, and the like.
2. Additives: Additives can adjust the activity and selectivity of the catalyst and improve the stability and life of the catalyst. Common additives include metal oxides, salts, etc.
3. Reaction raw materials: The catalyst needs to be in contact with the reaction raw materials in the process of promoting the chemical reaction. These reaction materials may be gaseous, liquid or solid, such as hydrocarbons, alcohols, acids, etc.

summary

catalysts play an important role in the field of chemical production raw materials, and their upstream and downstream related products are extensive. Upstream raw materials mainly include metals, non-metals and some compounds, and downstream applications involve petrochemicals, environmental protection and new energy. At the same time, the production and use of catalysts involves many related chemical products, such as carriers, additives and reaction raw materials.
