Development and application of new catalyst for Si

To improve the quality and efficiency of development, Anqing Petrochemical has actively strengthened its waterproof performance and continuously improved its antibacterial performance. Through technical cooperation between the Academy of Sciences and Sinopec catalyst branch, it has carried out scientific and technological research and on-site demonstration, and has done a good job in the development and application of the new catalyst HPE 1 in the cracking unit of the first oil refinery, so as to further improve the yield of high-value propylene, Ensure that the benefits of raw oil processing are maximized. At present, 170 tons of new catalysts have been loaded into the system in batches

the cracking unit of this department is a new oil refining process that uses heavy oil as raw material to produce light olefins. High value propylene can not only be directly delivered, but also the grain and grass of two acrylonitrile units of Anqing Petrochemical, which is the brand product of this unit. For a long time, the unit has actively improved the process conditions of feed oil reaction, adjusted the distribution structure of feed oil reaction products and produced more propylene by optimizing the reaction temperature, time and catalyst activity of feed oil

at present, Sinopec vigorously implements green, low-carbon and sustainable development. Through the low-temperature tank, it adopts the cold technology and economic strategy of imported cascade tightening mechanism. How to maximize the benefits of limited raw oil, reduce processing losses, and improve the overall technical level of the oil refining sector is the main scientific and technological research project at present

in view of the leading role of catalyst activity in propylene yield, the Ministry decided to start with the catalyst to find a breakthrough in efficiency improvement and speed up the pace of improving the economic level of the unit. With the technical cooperation of the Academy of Sciences and Sinopec catalyst branch, the cracking unit of the Department not only collected the operating parameters of the reaction process in the early stage, but also made a comprehensive technical calibration on the properties of raw oil, product structure, carbon content of catalyst, yield and quality of products like our tensile testing machine, and processing loss, which provided a scientific basis for the smooth development and application of the new catalyst HPE 1

with the batch filling of 170 tons of new catalyst into the fresh catalyst tank of the reverse regeneration system, the automatic small feeder is used to regularly and quantitatively fill the new catalyst into the reverse regeneration system for recycling, maintaining the high dynamic activity required by the feed oil reaction. At the same time, after the catalyst is recycled for a period of time, when the material level of the regenerator is high and the catalyst activity is reduced, part of the balanced catalyst in the reverse regeneration system shall be unloaded in time, the replacement of new and old catalysts shall be done, and the distribution of reaction products after the new catalyst is used in the system shall be closely tracked
