At present, the most important process in the oil refining and chemical industry is catalytic cracking. The catalysts used are all molecular sieves. For a long time, foreign research in this field has led several revolutions in the world's oil refining industry. Recently, the reporter was informed that in recent years, China's molecular sieve research has made significant progress, reaching the international advanced level in zeolite molecular sieve synthesis, mesoporous material research and other fields. The 15th International Molecular Sieve Conference, first organized by China, will be held in Beijing in August this year. .
The most widely used porous zeolite catalyst is in the petroleum refining industry. In the 1960s, the UOP company in the United States originally synthesized Y zeolite molecular sieves and successfully used gasoline for catalytic cracking of gasoline. Since then, a new reaction process designed based on the high activity and high selectivity characteristics of porous molecular sieve catalysts has quickly replaced the traditional IV catalytic cracking process using amorphous aluminum silicate as a catalyst, which not only improved the gasoline yield by 20%, The utilization rate of crude oil and the quality of oil products have been greatly improved. More importantly, the discovery of zeolite Y molecular sieves has changed the composition of human energy structures and chemicals.
Similarly, in the 1970s, U.S. Mobil Corporation invented the ZSM-5 molecular sieve, which also triggered a revolution in petrochemicals. In addition, porous molecular sieves have a wide range of separation performance and can separate long-chain n-alkanes from petroleum for the production of biodegradable detergents such as detergent powders, detergents, soaps, etc., thereby improving human survival. environment of. Not only that, the unique structure and properties of the porous molecular sieve material also make it a very promising application prospect in high-tech fields such as hydrogen, methane and other energy storage, environmental protection and treatment, biomedicine, etc., to chemical chemistry, materials science research Scientists and technicians have left a broad space for expansion.
Today, the research of porous molecular sieve materials has become a highly cross-disciplinary hotspot in many disciplines including chemistry, materials science, physics, and biology, and the research of porous molecular sieves is no longer limited to catalytic cracking, acid-base catalysis, and petrochemicals. Separation of molecules and the trend of penetration and transformation into high-tech fields such as energy, materials, information, and the environment. The application of porous molecular sieve materials has expanded from the traditional fields of 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 catalytic materials for molecular sieves in China, as well as catalytic conversion studies, have also been highly valued by the state. Since the 7th Five-Year Plan period, they have won major projects of the National Natural Science Foundation of China, national climbing plans and national major basic science projects. (973) and other projects have achieved a series of major scientific and technological achievements, especially in the zeolite molecular sieve synthesis, mesoporous materials research and other fields are at the forefront of the international academic community has a considerable position.
The 15th International Zeolite Screening Conference will be hosted by the International Molecular Sieves Association and the Molecular Screening Professional Committee of the Chinese Chemical Society. It will be hosted by Jilin University and the International Academic Exchange Center of the Chinese Academy of Sciences.
The International Zeolite Association (IZA) was established in 1973 and held once every three years. At the 13th General Assembly held in Montpellier, France in July 2001, under the joint efforts of our country’s scientific and technical workers, after fierce The competition successfully applied for the right to host the 15th International Zeolite Conference (15th IZC) to be held in 2007. This is the first time such a grand event has been held in my country. At that time, there will be experts and students from 54 countries and regions including the United States, Britain, France, Germany, Japan and Russia.
According to Prof. Ling Shilun, Vice President of Jilin University, the General Secretary of the General Assembly, the 15th International Zeolite Conference was held in China. It is not only an affirmation of the achievements and level of research in the field of molecular sieves in China for many years, but also promotes new technologies for petroleum refining, chemical conversion and chemical utilization worldwide. The development is of great significance. At the same time, it will also have a very positive impact on promoting the transformation of scientific research achievements in the international arena and promoting personnel training.
