At present, the most important process in the field of refining and chemical industry is catalytic cracking, and the catalysts used are all molecular sieves. For a long time, the research in this field abroad has led to several revolutions in the world's refining industry.

Recently, the reporter learned that in recent years, my country's molecular sieve research has made significant progress, reaching the international leading level in the fields of zeolite molecular sieve synthesis and mesoporous materials research. The 15th International Molecular Sieve Conference hosted by my country for the first time will be held in Beijing in August this year. Held.

Porous molecular sieve catalysts are most widely used in the petroleum refining industry.

In the 1960 s, the United States UOP company original synthesis of Y zeolite molecular sieve, successfully used in oil catalytic cracking gasoline.

Since then, the new reaction process based on the characteristics of high activity and high selectivity of porous molecular sieve catalyst quickly replaced the traditional type IV catalytic cracking process with amorphous aluminum silicate as catalyst, which not only increased the gasoline yield by 20%, but also greatly improved the crude oil utilization rate and oil quality.

More importantly, the discovery of Y zeolite molecular sieves has changed the human energy structure and the composition of chemicals.

Similarly, in the 1970 s, the Mobil company in the United States invented the ZSM-5 molecular sieve, which also triggered a petrochemical revolution.

In addition, porous molecular sieve has a wide range of separation performance, can be separated from the oil in the long chain n-alkane, used in the production of biodegradable detergent, such as washing powder, detergent, soap, etc., so as to improve the survival of human environment.

Not only that, the unique structure and properties of porous molecular sieve materials also make them have very good application prospects in high-tech fields such as hydrogen and methane energy storage, environmental protection and governance, and biomedicine. It has left a broad space for scientific and technological workers engaged in chemical and chemical engineering and material science research.

Nowadays, the research of porous molecular sieve materials has become a highly cross hot direction and field of many disciplines, including chemistry, materials science, physics, biology and so on,

Moreover, the research of porous molecular sieves is no longer limited to the catalytic cracking, acid-base catalysis and separation of small molecules in petrochemical industry, but shows a trend of penetration and transformation to high-tech fields such as energy, materials, information and environment.

The application of porous molecular sieve materials has expanded from traditional fields such as adsorption, separation, catalysis, and ion exchange to high-tech fields such as biomedicine, environmental protection and governance, and energy storage, and has become an advanced material worthy of people's expectation.

In recent years, the synthesis and preparation of molecular sieve catalytic materials and catalytic conversion research in my country have also received great attention from the country. Since the "Seventh Five-Year Plan", it has successively won major projects of the National Natural Science Foundation of China, the National Climbing Program and the National Major Basic Science With the support of the project, a series of major scientific and technological achievements have been achieved, especially in the fields of zeolite molecular sieve synthesis and mesoporous material research, it has a considerable position in the international academic community. The 15th International Molecular Sieve Conference will be hosted by the International Molecular Sieve Association and the Molecular Sieve Professional Committee of the Chinese Chemical Society, and will be specifically hosted by Jilin University and the International Academic Exchange Center of the Chinese Academy of Sciences.

The International Molecular Sieve Association was established in 1973 and is held every three years. At the 13th Congress held in Montpellier, France, in July 2001, with the joint efforts of Chinese scientific and technological workers, after fierce competition, it successfully applied for the right to host the 15th International Molecular Sieve Congress to be held in 2007.

This is the first time such an event has been held in our country. At that time, experts and students from 54 countries and regions, including the United States, Britain, France, Germany, Japan and Russia, will attend the meeting. According to the secretary-general of the conference, Professor Qiu Xilun, vice president of Jilin University, the 15th International Molecular Sieve Conference was held in China, which not only affirmed the research results and level of my country's molecular sieve field for many years, but also promoted global petroleum refining, chemical conversion and chemical utilization. The development of new technologies is of great significance,

At the same time, it will also have a very positive impact on promoting the transformation of scientific research results on an international scale and promoting the training of talents.

At the same time, Fulong has been committed to the research and production of molecular sieves, and adhere to the quality as the root, integrity-based, scientific management, innovation and development. Create a better tomorrow.
