Molecular sieve development status
Research on molecular sieve of oil refining catalyst in my country reaches international level
Currently the most important process in the field of oil refining and chemical cracking, the catalysts used are all molecular sieves. Foreign research in this field has led several revolutions in the world oil refining industry.
Recently, the reporter was informed that in recent years, China’s molecular sieve research has made significant progress, and has reached the international advanced level in the fields of zeolite molecular sieve synthesis and mesoporous material research. The 15th International Molecular Sieve Conference hosted by China for the first time will be held in Beijing this August .
Porous molecular sieve catalyst is the most widely used in petroleum refining industry.
The original synthetic Y zeolite molecular sieve of UOP in the United States in the 1960s was successfully used in the catalytic cracking of petroleum to produce gasoline.
Since then, the new reaction process designed based on the high activity and high selectivity of porous molecular sieve catalysts quickly replaced the traditional type IV catalytic cracking process using amorphous aluminum silicate as the catalyst, which not only increased the gasoline yield by 20%, Significantly improved the crude oil utilization rate and oil quality,
More importantly, the discovery of Y zeolite molecular sieve has changed the structure of human energy and the composition of chemicals.
Similarly, in the 1970s, Mobil Corporation of the United States invented the ZSM-5 molecular sieve, which also triggered a revolution in the petrochemical industry.
In addition, the porous molecular sieve has a wide range of separation performance, can separate long-chain n-alkanes from petroleum, and is used to produce biodegradable detergents, such as washing powder, detergent, soap, etc., thereby improving the survival of human beings. environment of.
Not only that, the unique structure and properties of porous molecular sieve materials also make it have a very good application prospect in high-tech fields such as hydrogen, methane and other energy storage, environmental protection and governance, biomedicine, etc. Science and technology workers have left a broad space for expansion.
Nowadays, the research of porous molecular sieve materials has become a highly intersecting hot direction and field in multiple disciplines including chemistry, materials science, physics, biology, etc.
And the research of porous molecular sieve is no longer limited to the catalytic cracking of petrochemical industry, acid-base catalysis and the separation of small molecules, but presents a tendency to penetrate and transform into 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 treatment, and energy storage, and has become an advanced material worthy of people's expectations.
In recent years, the synthesis and preparation of molecular sieve catalytic materials and catalytic conversion research in China have also received great attention from the state. Since the "Seventh Five-Year Plan", they have been awarded major projects of the National Natural Science Foundation of China, the National Climbing Plan and major national basic science projects. The project support has achieved a series of major scientific and technological achievements, especially in the fields of zeolite molecular sieve synthesis and mesoporous material research, which are at the international frontier and have 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 held every three years. At the 13th Congress held in Montpellier, France in July 2001, with the joint efforts of our scientific and technological workers, after fierce competition, it succeeded To apply for the right to host the 15th International Molecular Sieve Conference to be held in 2007.
This is the first time such a grand event is held in our country. There will be experts and students from 54 countries and regions including the United States, Britain, France, Germany, Japan, and Russia. According to Professor Qiu Shilun, Vice President of Jilin University, the 15th International Molecular Sieve Conference was held in China, which is an affirmation of the research achievements and levels of China's molecular sieve field for many years, and a new technology for promoting global petroleum refining, chemical conversion and chemical utilization 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 talent training.
At the same time, Fulong has been committed to the research and production of molecular sieves, and adheres to quality as the root, integrity-based, scientific management and innovative development. Create a better tomorrow.
