Molecular Sieve is Very Important in Petrochemical and Refinery Industries

More than 80% of the processes in the chemical industry involve catalytic technology, especially for the refining and petrochemical industries, catalysts are indispensable, and zeolite molecular sieves are an important member of them. The industrial catalytic application of zeolite molecular sieves began in the 1960s, Mobil Corporation It was first discovered and used faujasite zeolite to replace amorphous silica-alumina catalyst, which was used in the catalytic cracking (FCC) process in oil refining, which greatly improved gasoline production and crude oil utilization . At present, only as an FCC catalyst, zeolite molecular sieve catalyst Its sales accounted for 18.5% of the global catalyst.

Zeolite molecular sieves have a definite pore system, large intracrystalline specific surface area and acidity comparable to that of sulfuric acid or aluminum chloride, and have the advantages of molecular sieving or shape selection, as well as being modifiable or easy to doping, etc. They are suitable for many industrial catalytic reactions. It has an efficient promotion effect, and has been widely used in the continuous innovation and development of oil refining and petrochemical technology. Therefore, it is urgent to develop heavy oil refining technology and new technologies for the production of petrochemical products using new resources such as coal chemical industry and for a period of time in the future. , low-value by-product high-efficiency conversion technology, characteristic high-value-added petrochemical product production technology, low-energy or low-material consumption technology, and CO2 chemical utilization technologies, and the development of these new technologies is inseparable from the innovation and development of catalysts. Including molecular sieve catalysts. Thinking from the perspective of industrial catalysis, focusing on the goals of efficient and comprehensive utilization of resources, energy saving and consumption reduction, atomic economy and environmental friendliness, how to further improve the performance and efficiency of molecular sieve catalysts, and whether the design and preparation of molecular sieve catalysts can be controlled, molecular sieve The economical production process and the new catalytic application of molecular sieve
