Ten years of great development in chemical technology, praising China's prosperity and strength in the prosperous age, and making the world more lively and exciting with everyone's participation. [Ten Years of Great Development of Chemical Equipment] Continuously update the summary post, welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Enhance quality awareness and promote high-quality development----------------------------------------- "The latest evaluation results show that the service life of the catalyst has been nearly doubled. ”Recently, Fan Jinlong, director of the Chemical Engineering Office of the Research Institute of Urumqi Petrochemical Company, informed the process workshop that the second-generation carbon pentaolefin skeleton isomerization catalyst has achieved good results in this round of life cycle improvement tests. 　　In May this year, the second-generation carbon pentaolefin skeleton isomerization catalyst independently developed by Wuhan Petrochemical was successfully loaded into the isomerization unit of the etherification unit of the light hydrocarbon workshop of Wuhan Petrochemical Refinery. It can effectively increase the output of methyl tert-amyl ether and provide blending components for the production of high-grade gasoline. 　　“Catalysts are the foundation and core of the petrochemical industry. They need to constantly adapt to production requirements and upgrade their performance. ”Fan Jinlong said that on the road of technological innovation, the low-hanging fruits have been picked, and scientific researchers must focus on the high-hanging fruits. 　　Since 2022, Wuhan Petrochemical has accelerated the improvement and upgrading of catalysts, developed a preparation method for the second-generation carbon pentaolefin skeleton isomerization catalyst, changed the catalyst structure, and reduced pollutant emissions during the production process. While improving performance, it has reduced the production cost by nearly 20% compared with the first-generation catalyst. 　　In order to ensure that the second-generation carbon pentaolefin skeletal isomerization catalyst can be scaled up for production, the research team of the institute has done a lot of research and preparation work. R&D personnel screened more than 150 raw material formulas, selected appropriate bonding aids, catalyst roasting methods and temperatures, and optimized the catalyst preparation process. 　　Just one step away from success, the research team encountered unexpected difficulties - in the industrial scale-up test, some key parameters of the catalyst did not match the laboratory results. 　　Faced with the high cost of scientific research in industrial scale-up tests and the urgent need for enterprises to improve quality and efficiency, scientific researchers repeatedly compared the sample analysis results in industrial scale-up tests with laboratory results. During the day, they went to the device site and followed the production team to keep an eye on the process parameters. At night, they returned to the laboratory for simultaneous verification and troubleshooting the causes of abnormalities. Eventually, they discovered that the problem lay in the roasting part of the experiment. 　　In order to accurately control the baking temperature of the catalyst in the device, the research team introduced expansion blocks used for firing in the ceramic industry, which solved the problem of inaccurate temperature measurement inside the reactor during the industrial scale-up test. After one year and four rounds of verification, the research team conducted a total of 6,000 hours of evaluation tests, corrected parameters such as oxygen content and temperature at each stage during the catalyst roasting process, and achieved industrial scale-up production in February this year. “The road to innovation is not easy to follow, and you will often encounter obstacles and even failures. But we must strengthen our confidence in innovation while overcoming difficulties and solving problems. ”Asked about the innovation process, Chen Lantian, a member of the research team, said. 　　At present, the isomerization unit of Wu Petrochemical's etherification unit has completed maintenance and started production, and the new catalyst is undergoing the ultimate verification of actual production. The company will continue to target product iterative upgrades, strive to set catalyst benchmarks, and empower industrial green development.
