At present, the most important technological catalytic cracking in the field of oil refining and chemical industry, all the catalysts used are molecular sieves, and the research abroad in this field has led several revolution in the world's refining industry.
Porous molecular sieve catalysts are widely used in petroleum refining industry. In 1960s, the original Y zeolite molecular sieve made by UOP company in the United States was successfully applied to the catalytic cracking of petroleum to produce gasoline. Since then, the new reaction process based on the high activity and high selectivity of the porous molecular sieve catalyst quickly replaced the traditional catalytic cracking process with amorphous aluminum silicate as the catalyst, which not only increased the gasoline yield by 20%, greatly improved the crude oil utilization and quality of the oil, but more importantly, Y zeolite. The discovery of molecular sieves has changed the structure of human energy and the composition of chemicals.
Similarly, in the 70s of last century, the Mobil company of the United States invented the zem 5 zeolite, which also led to a revolution in petrochemical industry. In addition, porous molecular sieves have extensive separation performance.
In recent years, the synthesis, preparation and catalytic conversion of molecular sieve catalytic materials in Feizhou have also been paid great attention by the state. Since 1987, a series of important projects of National Natural Science Foundation have been obtained, and the support of national climbing program and national major basic science projects has been made a series of emphasis. Large scale scientific and technological achievements, especially zeolite molecular sieve synthesis, mesoporous materials research and other fields are at the forefront of the world
