On April 25, the cracked gasoline series hydrogenation catalyst of China Petroleum and Petrochemical Research Institute has covered all domestic ethylene users such as PetroChina, Sinopec, CNOOC, and Chemical China. . On April 16, the C2 pre-depropanization and pre-hydrogenation catalyst independently developed by the Petrochemical Institute was successfully launched in Daqing Petrochemical for its first industrial application test. This marks a key step in the independent innovation of China Petroleum’s catalytic cracking catalyst technology, design and other complete sets of technologies, and the integration of “production, marketing and research” has reached a new level.
On April 10, the Petrochemical Institute independently developed the first-stage nickel-based hydrogenation catalyst LY-2008 for cracked gasoline, the second-stage hydrogenation catalyst LY-9802, and their grading agents. Won the international bidding for the second phase of the 1.2 million tons/year ethylene project of CNOOC and Shell Petrochemical Co., Ltd. and the pyrolysis gasoline hydrogenation catalyst. This is another successful promotion in Sino-foreign joint ventures after Fujian United and Yangzi BASF. It is the first domestic installation of an ethylene plant with a scale of more than 1 million tons per year and the first use of domestic pyrolysis gasoline hydrogenation catalysts.
On April 16, the industrial application experiment of the C2 pre-depropanization and pre-hydrogenation catalyst was successfully started, following the ethylene unit cracking gasoline hydrogenation, acetylene post-hydrogenation, and MTO After installing acetylene hydrogenation and polyethylene raw material hydrogenation and refining catalysts, the “fifth golden flower” developed by the Petrochemical Institute in the field of series catalysts for the ethylene industry shows that PetroChina has taken another step forward in the independent development of large ethylene technology.
Carbon dioxide pre-hydrogenation is a new process produced by large-scale ethylene technology. The material composition is complex, and imported products have been used in China for a long time. In 2007, the Petrochemical Institute began small-scale trial development of catalysts, and then cooperated with Daqing Petrochemical to establish a project and decided to conduct industrial testing in a 270,000 tons/year ethylene-stage carbon dioxide hydrogenation reactor. During this start-up, the research and development team of the Petrochemical Institute and Daqing Petrochemical Cooperation Project pioneered a plan to start the operation directly without charging CO. The export products reached the standard in 2 hours, and the device process parameters were stable in 4 hours. Under the working conditions with large fluctuations in the composition of the reaction materials , the reactor operates stably and meets the device requirements, and the catalyst performance is praised by the application manufacturers.
