Molecular sieve manufacturer explains the application of molecular sieves in petrochemical industry

Since the advent of molecular sieves for more than half a century, the development of related technologies is mainly used to meet the needs of three traditional fields. required ion exchange process, etc. The application of molecular sieves in the petrochemical field continues to expand, which promotes the rapid development of my country's economy. In petrochemical industry, it is mainly used for petroleum cracking, ethylene, propylene drying, natural gas drying, CO2 desorption, hydrocracking purification, etc. Next, the molecular sieve manufacturer will explain how it is used.

1. Adsorbent

Divided by function, molecular sieve materials with adsorption capacity are mainly used in chemical and environmental purification and separation industries, as well as desiccant and other related fields. Because the physical adsorption of molecular sieve materials can adsorb substances, the internal pores have strong polarity and Coulomb field, which can adsorb polar molecules and unsaturated molecules, and water-absorbing materials are used in industrial and environmental separation, purification and drying fields. Molecular sieves can be used as adsorbents to remove heavy metal ions in wastewater treatment, and can treat organic wastewater. Modified molecular sieves can remove compounds in water with good results. In the field of gas separation, molecular sieve adsorbents can be used for pressure swing adsorption to produce nitrogen, CO2 and oxygen, and molecular sieve adsorbents are also good oil cleaners.

2. Catalyst

As catalytic materials, molecular sieve materials with catalytic function are mainly used in petrochemical industry, coal industry and fine chemical industry. Quantity is large.

In order to effectively contain molecules inside the molecular sieve, the pore size of the zeolite molecular sieve should be larger than that of the reactant molecules, but should not exceed a certain range. The acid catalyzed reaction occurs in the catalytic process, and effective molecules are required to form a complete catalytic process.

3. Ion exchanger

Molecular sieve materials with ion exchange capacity are mainly used in detergent industry, mining industry and waste treatment and other related industries, ion exchange materials are used in detergent industry, mines and radioactive waste and liquid waste treatment.
