China Youth News · China Youth Network reporter Hu Chunyan a arsenic, b honey.With this sentence to describe aromatics and human “love each other to kill”, but also a bit appropriate.Aromatic hydrocarbons, with their pleasant name, are important chemical basic raw materials and are closely related to everyone’s life.Clothing fabrics, building materials, rubber and fiber, which people cannot live without, are all synthesized from aromatic hydrocarbon resources.However, it is also a human health “killer”.When too much of it “blends” into gasoline and diesel, it makes the oil less combustible and produces large amounts of fine particles.Studies have shown that particulate matter containing POLYcyclic aromatic hydrocarbons is toxic, mutagenic and carcinogenic.How to make aromatic hydrocarbons quickly and efficiently go to the most appropriate place to contribute value to mankind?After years of scientific research, the young scientific research team of Cnooc Tianjin Chemical Research and Design Institute has developed the world’s first diesel aromatics adsorption separation technology, which has been applied in one million tons and a complete set of whole process.34, li bin of the molecular sieve synthesis and application research director, he explained that the technology magic bridge between oil and chemicals, gasoline and diesel fuel efficient can be converted to the market shortage of aromatics and olefins, green solvent, such as chemicals, let oil chemical composition of his each “everything, can”.According to the projects that have been put into production, this technology has improved the production efficiency of petroleum refining by more than 1/3 compared with the traditional way, and also has the advantage of green environmental protection. This technology has been granted 48 national authorized invention patents and 1 international authorized invention patent.Yu Haibin, president of the institute, said it is of great significance to promote the transformation and upgrading of China’s refining and chemical industry and help achieve the goal of “dual carbon”.Part of the r&d team of the world’s first diesel adsorption separation technology.China’s crude oil is mainly heavy oil and inferior oil. The content of aromatic hydrocarbons, especially polycyclic aromatic hydrocarbons, is very high in the refined oil.The secondary processing process of petroleum refining in China accounts for an important proportion of catalytic cracking, and the content of POLYcyclic aromatic hydrocarbons in diesel oil produced by this processing method is also high.For a long time, how to reduce aromatics content in diesel oil has been a difficult problem for refineries.In recent years, China’s refining and chemical industry is faced with a new problem thrown by The Times — overproduction of refined oil products while refineries desperately want to drive out aromatic hydrocarbons from oil products and improve the output of clean oil products.At present, the main products of China’s oil refining industry are gasoline and diesel oil, and the yield of chemical products is low.With China’s slowing economic growth and rapid development of alternative energy sources, diesel consumption demand has already reached its peak, and gasoline consumption demand will also peak in 2025, li said. The problem of excess refined oil products is serious, and industrial transformation and upgrading are urgently needed.At the same time, with the continuous improvement of people’s living standards, the demand for olefins, aromatics and other chemical raw materials continues to increase.It has become the focus of the whole industry to develop relevant oil and chemical combination technologies, realize the high-value utilization of excess oil products, and promote the transformation and upgrading of traditional refining and chemical industry and improve quality and efficiency.”How to use the aromatics in excess diesel oil to increase the production of aromatic chemicals, this is the technology we have been studying.”Aiming at this direction, Li Bin and the team buried themselves in the key, a dry is 8 years.They creatively put forward the idea of diesel adsorption separation technology to separate aromatic hydrocarbons directly from oil.This is a subversion of the process of traditional refining industry.Li Bin is in charge of adsorbent development, he explained the difference in the most popular way, that is, in the past, chemical method, through a series of reaction procedures, unified change of petroleum molecular structure to get the corresponding petroleum products.And now through the physical separation method, “skip” the traditional refining distillation, catalytic cracking and other processes, with adsorbent directly according to the molecular structure of petroleum classification and processing, low cost, high efficiency to achieve accurate and efficient separation of oil components.Using the idea of rolling yuanxiao to solve the worldwide problem of adsorption separation is not a new concept, but the adsorption separation of aromatic hydrocarbons in diesel oil, no one has walked this road before.The selection of diesel adsorption material is the key technology, its molding is a worldwide problem, there is no precedent to follow.At the beginning of the project, Li bin and his team have been looking for the ideal adsorption separation material. They have made numerous attempts in the laboratory, and sometimes even lived in the laboratory, but they have not received satisfactory results.Many innovations have a “aha” moment.Li Bin said with a smile, is the so-called magic cook is not a good engineer, the conquest of this worldwide problem, the inspiration is from the kitchen steaming hot air floating out.After work that day, Li Bin received a message from his wife: “I want to eat yuanxiao tonight.”Li Bin bought the lantern and boiled it in a pot when he came home.Staring at yuanxiao rolling in the water, Li Bin’s mind was full of adsorbent in the laboratory during the day. Suddenly, a bold idea popped out: The adsorbent forming and rolling yuanxiao are the same idea!In this way, he tried to introduce modified starch into the adsorption separation material, with high viscosity hydrophilic additives to make the adsorbent powder into small balls, the world problem of adsorption material molding was solved.Diesel adsorption material is a particle size of 0.4-0.8mm microspheres, the size of millet, but its strength is very high.Li bin said that the size of the microsphere is also determined after numerous experiments, the best solution. “A little bigger, the flow rate of oil through the slower, lower efficiency;Anything smaller would be hard to engineer.”Compared with the traditional oil production process, which produces gas and water emissions, this adsorption and separation production process is green and environmentally friendly. The organic solvents generated can be recycled and reused without waste discharge, which is very friendly to the environment.The average age is about 30 years old, and the youngest is 24 years old. A scientific and technological innovation must go out of the laboratory to complete the industrial application of the last “leap”, before it can truly realize its innovation value.In 2020, the world’s first industrial demonstration plant using diesel adsorption separation technology realized full capacity production in Binhua, Shandong province.This marks a solid step towards the comprehensive application of the world’s first diesel adsorption and separation technology, which is based on the concept of “molecular engineering”, Yu said.At present, the institute has completed technical exchanges with more than 40 enterprises, among which 3 projects of one million tons have been approved, with a total processing scale of more than 5 million tons per year.It doesn’t sound that hard.In fact, the research and development of this technology began in 2013, and it took eight years from the development of the technology to the approval of the project, and then to the final industrial application.In Li bin’s opinion, the road of scientific research is lonely and requires constant trial and error, “but I always believe that this road will be successful.”The average age of the team is about 30, and the youngest is only 24.In the eyes of outsiders, this is a team full of energy and combat.”Adsorption separation” is nicknamed as “daughter-in-law separation” by Li Bin’s team: in recent years, the core team members of the project team are on business trips for about 200 days every year, and Li Bin and colleagues in charge of production and application are even on business trips for more than 200 days.The engineering men rarely complain, but they use humor to overcome the pain of being separated from their families for a long time. “It can be said that we exchanged our separation from our wives for the success of the adsorption separation technology.”Li Bin said with a simple smile.Li Bin is glad that his scientific research has caught up with the major needs of the development of the country and industry.He plans to further expand the application field of diesel adsorption separation technology, develop relevant industrial chain extension technology, and create a series of complete sets of technologies combining oil and chemical.”Our generation should shoulder the responsibility of transforming and upgrading oil refining and chemical industry,” he said.Source: China Youth Daily client
