Breakthrough in hydrocracking technology of PetroC

PetroChina's hydrocracking technology has made a breakthrough

the hydrocracking catalyst (phc-03), independently developed by the China Petroleum and Petrochemical Research Institute, was successfully started up in Daqing Petrochemical's 1.2 million ton/year hydrocracking unit a few days ago, and qualified products were produced after 17 hours of feeding, which is another major technological breakthrough in the research and development of PetroChina's full range of catalysts for oil refining

the operation results of the industrial unit show that the technical indicators of the catalyst fully meet the requirements of the unit, and the indicators of diesel oil, light naphtha, hydrocracking tail oil and other products meet the requirements of relevant standards. Under the conditions of cracking reactor average temperature 368 ℃, reaction pressure 13.5mpa, hydrogen oil volume ratio 1200 ∶ 1 and cracking agent volume space velocity 1.5/h, the straight run wax oil raw material is processed. The heavy naphtha yield is 24.92%, the sulfur and nitrogen content is less than 0.5 μ g/g, and the aromatics potential content is 42.5%. It is a high-quality reforming feed; The yield of diesel oil is 44.06%, cetane index is 73.4, and the content of sulfur and nitrogen is less than 2 μ g/g, which meets the Euro V diesel standard; The yield of tail oil is 26.37%, If BMC wants to destroy the sample (for example, the tensile I value is 4.5, which is a high-quality ethylene cracking raw material. The production data shows that the catalyst fully meets the production technology needs.

it is reported that the hydrocracking technology marks the level of hydrogenation technology, and its key and core catalyst has been monopolized by foreign countries. The research and development of the catalyst has gone through ten years, and the scientific researchers have gone through small-scale test, pilot test, ton scale trial production, as well as simulation and evaluation of 12 working conditions, and have creatively developed molecules Sieve synthesis, modification and compounding technology have solved the technical problem of reasonable matching of cracking and hydrogenation functions. The developed catalyst has the characteristics of good activity, high selectivity and strong activity stability, which ensures the product yield, product distribution and product quality of hydrocracking. The latest LCA verification complies with ISO standards, and finally forms the hydrocracking technology with independent intellectual property rights of PetroChina
