of upstream and downstream related products
of petroleum coke Petroleum coke is an important raw material for chemical production, which is widely used in aluminum, steelmaking, chemical fertilizer, glass, ceramics and other industries. As a by-product in the refining process, the yield and quality of petroleum coke are affected by the nature of crude oil, refining process and other factors. In the field of raw materials for chemical production, petroleum coke is rich in upstream and downstream related products, some of which are described in detail below.

1. upstream products

1. crude oil

petroleum coke upstream raw material is mainly crude oil. Crude oil is a complex mixture of carbon, hydrogen, nitrogen, oxygen, sulfur and other elements. Various fractions and residues are separated through the refining process, and petroleum coke is one of the residues.

2. Refining catalyst

refining catalyst also has an important influence on the production of petroleum coke. Different catalysts will affect the reaction rate and product distribution of the oil refining process, thereby affecting the quality and yield of petroleum coke.

2. downstream products

1. Aluminum carbon

Petroleum coke is one of the main raw materials for the production of aluminum carbon. Carbon for aluminum includes pre-baked anode, cathode carbon block, etc., used in electrolytic aluminum industry. Pre-baked anode as anode material in the process of aluminum electrolysis needs to have the advantages of high temperature strength, good conductivity, thermal shock resistance and so on. The ash content and sulfur content of petroleum coke have important influence on the quality of pre-baked anode.

2. Carbon

for the steel industry Petroleum coke can also be used for the production of carbon for the steel industry, such as blast furnace carbon blocks, electric furnace carbon blocks, etc. These carbon products are used as refractory and conductive materials in the steel smelting process, which have an important impact on the normal operation of the furnace and the quality of steel.

3. Chemical fertilizer with carbon

Petroleum coke can also be used for the production of chemical fertilizer with carbon, such as synthetic ammonia furnace with carbon. These carbon products are used as catalyst carriers and reactor internals in the fertilizer production process, which have an important impact on the production efficiency and product quality of fertilizers.

4. Carbon

for glass industry Petroleum coke can also be used for the production of carbon for glass industry, such as carbon for glass kiln. These carbon products are used as refractories and thermal insulation materials in the glass production process, and have an important impact on the stability of the glass melting process and product quality.

In short, as an important raw material for the production of chemicals, petroleum coke has a wide range of upstream and downstream related products, involving many fields, such as aluminum, steel, fertilizer, glass, etc. The quality and performance of these related products are often affected by the quality and index of petroleum coke. Therefore, the quality of petroleum coke needs to be strictly controlled in the production process to ensure the quality and performance of the final product.
