Biography
Liu Zhongmin, born in 1964, was born in Zhoukou, Henan, academician of the Chinese Academy of Engineering, and director of the Dalian Institute of Chemistry and Physics of the Chinese Academy of Sciences.According to the characteristics of my country’s energy endowment, Liu Zhongmin led the team to develop methanol’s olefins (DMTO) technology to cooperate with industrial experiments and industrialization.He has won the first prize of the National Technology Invention Award, the first prize of the National Science and Technology Progress Award, the outstanding science and technology achievement award of the Chinese Academy of Sciences, and the most beautiful science and technology worker.
Some time ago, Liu Zhongmin, an academician of the Chinese Academy of Engineering and the director of the Dalian Institute of Chemistry and Physics of the Chinese Academy of Sciences (hereinafter referred to as the “Dalian Chemical Institute”), has traveled to Beijing and Dalian.Although it was hard, Liu Zhongmin felt worth it.”‘Key clean energy and demonstration’ technology special projects have just been settled. This 5 -year project has exceeded 63 key technologies including new generation of methanolized olefins.100 million yuan, “Liu Zhongmin said.
As the person in charge of this science and technology project, since entering the field of coal -to -methanol olefin research in the 1980s, Liu Zhongmin has been engaged in the foundation and application research of catalysts and new catalytic processes, obtained a number of world -class innovation achievements and realized industrialization.It has played an important role in promoting the use of coal cleaning.
Study the “use of coal -to -oil” technology and improve the coal through methanol to make an olefin
Olefin is one of the important basic industrial chemicals, and it was mainly refined from oil in the past.
“In the 1970s, many countries launched a scientific and technological research plan for coal through methanol -making olefin technology.” Liu Zhongmin said that in 1983, he graduated from the Department of Chemistry of Zhengzhou University and went to the Dalian Institute of Chemistry. The subject, “my country’s resource endowment is rich in coal and poor oil. Therefore, it is of great significance to carry out the research of” coaling oil “technology.”
After graduating from a PhD in 1990, Liu Zhongmin officially joined the Dalian chemicals and coal through the research team of methanol to make an olefin research team, and served as the deputy team leader of the research team in the following year. “At that time, some people suggested that I go abroad for development.Still choose to stay. “
Why stay?”The relay stick of coal -to -olefin research is passed on to my hand, and I must pick up this stick.” Liu Zhongmin said, “If you can study the” coal -to -oil replacement “technology at an early date, it will be a great thing!”
The coal -to -olefin is divided into two steps. First, coal is used to synthesize methanol with coal, and then olefins are used by methanol.”At that time, coal synthetic methanol had mature industrial technology, but methanol -making olefin was a challenging research direction worldwide.” Liu Zhongmin recalled.
Liu Zhongmin’s main direction at that time was a di methar ether.”Both methal ether is a dehydrated product of methanol. The principle and catalytic process of the two transformed into an olefin is basically the same.” Liu Zhongmin said.
Catalyst technology is the first problem to be solved.At that time, there were two technical routes of ZSM -5 molecular sieving catalysts and SAPO -34 molecular sieve catalysts. The former has an example of industrial applications. The risk is relatively small. For industrial applications of SAPO -34 molecular sieve catalyst, further research is needed.After careful analysis, Liu Zhongmin decided to “walk two legs”.With the deepening of research, he and the team discovered that the industrial application prospects of SAPO -34 molecular sieve catalysts were actually better.
Failure, research; failure again, continuing to study … In 1995, Liu Zhongmin led the team to complete the pilot test of 60 tons of olefin in an annual output of “synthetic qi through di met metropolitan ether.”This achievement was ultimately won the “Eighth Five -Year Plan” major scientific and technological achievement award jointly awarded by the Chinese Academy of Sciences Science and Technology Progress Award, as well as the “Eighth Five -Year Plan” major scientific and technological achievement award jointly awarded by the former National Family Planning Commission, the National Science and Technology Commission and the Ministry of Finance.
“At this moment, international oil prices have fallen sharply. Compared with petroleum -made olefins, coal -to -olefin costs are too high. Enterprises are unwilling to invest, and there are no other sources of funds. How to continue researching into a problem.” Liu Zhongmin said that in the face of difficulties, in the face of difficulties, Only persist.
In 1998, Liu Zhongmin scored a scientific research funding from the Chinese Academy of Sciences, and he and his team continued to conduct research.They figured out the reaction mechanism of the methanol’s olefin process, and continuously improved the process production technology on the basis of this.
Complete the 10,000 -ton industrial test, and continue to promote technical optimization and upgrade
A new process in the chemical industry usually takes multiple rounds of experiments and improvement, from laboratory to trial to industrial demonstration production, and finally industrialization can be industrialized.
“In those years, while we were doing technological research and development, we also had to find financial support everywhere.” Liu Zhongmin recalled, “How to let companies understand our technical prospects and potential advantages and persuade them to support the construction of 10,000 -ton industrial test devices.big.”
In 2004, international oil prices began to pick up, and the application of methanol’s olefin technology ushered in new opportunities.In this year, using the world’s leading methanol -making olefin technology developed by Dalian chemicals, Shaanxi Province has built a 10,000 -ton industrial test device in Huaxian County (now Huazhou District), Weinan City.
“For us, such a large -scale experiment has never been. If the test is successful, it means that we have the ability to compile a million -ton device set of craft packages.” Liu Zhongmin said.
More than 700 days and nights, a dozen people in the team insisted on the test site, climb up and down on the device of tens of meters high every day, busy with the test.Finally, in August 2006, the experiment was successful: the relevant technical indicators were advanced, and 75 tons of methanol were transformed daily.
Subsequently, Liu Zhongmin’s team reached a cooperation with Shenhua Group to sign a technical license contract of 600,000 tons/year methanol low -carbon olefin.In August 2010, Shenhua Group Baotou methanol -making olefin -making olefin technology industrial devices were made in a trial and successful. my country achieved a breakthrough in key technologies and industrial applications in this field.
“As of now, the methanol -making olefin series technology has signed a technical implementation license contract for 32 sets of devices, with an olefin production capacity of 21.6 million tons/year; 17 sets of industrial devices that have been put into production, with an olefin production capacity of more than 10 million tons/year, and new output value.About 100 billion yuan each year. “Liu Zhongmin proudly listed these numbers.
Today, under the continuous exploration and optimization of Liu Zhongmin’s team, methanol’s olefin technology has grown to the third generation.”Single -sets of the third -generation technology have increased significantly, the cost of unit olefin is about 10%, the energy consumption has decreased significantly, and the economic benefits have improved significantly.” Liu Zhongmin introduced.
Research research and research continuously, develop new coal -based ethanol technology
It seems that the problem of methanol’s olefin technology seems to be “relieved”, but Liu Zhongmin has not stopped here.While developing coal -to -olefin technology, he also aimed at the “coal -to -ethanol” as a challenging and widely used technology.
“The scientific research results can meet the needs of economic and social development. Such scientific research is more valuable.” Liu Zhongmin introduced. “At present, the world’s ethylene production is mainly prepared by biomass raw materials such as grainPreparation of ethanol is not suitable for large -scale promotion. “
In 2012, the Dalian Chemical Institute and Shaanxi Extended Petroleum (Group) Co., Ltd. cooperated to carry out the research and development of the “Synthetic Gas Ethanol Craft Technology” project.In January 2017, the world’s first 100,000 -ton/annual coal -based ethanol industrial demonstration project with independent intellectual property rights to complete the full process test was completed to produce qualified water -free ethanol.
As of now, the coal -based ethanol technology has signed 12 technical license contracts. Ethanol capacity has reached 3.75 million tons/year. The emerging industries of coal -based ethanol have been embossed.This is of great significance to ensure my country’s energy security, food security, and achieve the “double carbon” goal.
In recent years, helping the achievement of carbon peaks, carbon neutrality, and the goal is the key topic of Liu Zhongmin’s continuous attention.In 2019, the Dalian Institute of Chemical Institute and the advantages of the energy field of the Chinese Academy of Sciences led the establishment of the Institute of Clean Energy Innovation of the Chinese Academy of Sciences. Liu Zhongmin served as the dean; in 2023, the Ministry of Science and Technology established the first National Carbon Zhonghe Science and Technology Expert Committee, and Liu Zhongmin served as the team leader.”The realization of the” double carbon “goal is a gradual process. I hope we can make more contributions to the promotion of high -quality development of green.” He said.
For more than 40 years in the energy field, the young guy of that year was already pale.”I am just one of the majority of science and technology workers.” In July 2023, Liu Zhongmin was selected as “the most beautiful science and technology worker”. He said humblely, “This is not only a commendation for my personal performance, but also for my personal performance, but also for my personal performance, but also for my personal results, but also for my personal performance, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal performance, but also for my personal results, but also for my personal performance, but also for my personal results, but also for my personal performance, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal performance, but also for my personal results, but also for my personal results, but also for my personal results, but also for my personal performance.The recognition of our team’s work. Scientific research is a relay race, we must continue to complete. “
