1. Molecular sieve petrochemical field

catalytic cracking

Function: Molecular sieve, as an important component of catalytic cracking catalyst, can crack heavy oil into light oil products such as gasoline and diesel, and improve the quality and output of petroleum products.

Advantages: Molecular sieve catalysts have high activity, high selectivity and good stability, which can significantly improve the efficiency and product distribution of catalytic cracking reactions.

Hydrocracking

Function: During the hydrocracking process, molecular sieve catalysts can promote the hydrogenation and cracking reaction of hydrocarbon molecules and produce high-quality clean fuel.

Application: Widely used in the petroleum refining industry to meet the market's demand for high-quality fuels.

Isomerization reaction

Function: The molecular sieve catalyst can catalyze the isomerization reaction of hydrocarbon molecules, improve the octane and hexadecane values of the fuel, and improve the combustion performance of the fuel.

Application: Play an important role in the production process of gasoline and diesel.

2. Field of molecular sieve natural gas treatment

Natural gas dehydration

Function: Molecular sieve has strong water absorption, can effectively remove moisture from natural gas, prevent hydrate formation and pipeline corrosion.

Application: Widely used in dehydration treatment during natural gas mining, transportation and processing.

Natural gas desulfurization

Function: Some types of molecular sieves (such as 13X molecular sieves) have selective adsorption ability to acid gases such as hydrogen sulfide and can be used for desulfurization of natural gas.

Application: Improve the quality and safety of natural gas and meet environmental protection requirements.

Natural gas decarbonization

Function: Molecular sieve can also adsorb impurity gases such as carbon dioxide in natural gas to achieve purification and purification of natural gas.

Application: It is particularly important in the production process of liquefied natural gas (LNG).
