The FC-28 single stage high-pressure oil hydrocracking catalyst developed by the Fushun Research Institute of Petroleum and Chemicals recently passed the technical appraisal hosted by the Ministry of Science and Technology Development of Sinopec. According to the appraisal, FC-28 single-stage high-pressure oil hydrocracking catalyst has high selectivity, good stability, and better activity than amorphous catalysts, reaching the current international advanced level of similar catalysts.
In recent years, as the single-stage hydrocracking process is simple, the investment is small, the operation is simple, the product structure during the operation is stable, and the middle distillate oil has good selectivity, and it is widely used not only in a device for producing a middle distillate in the largest amount, but also Good promotion prospects and development potential.
In order to meet the needs of middle and distillate production in China's refineries, Fuxi Academy has developed high activity, high middle distillate selectivity based on the development of single-stage catalysts such as ZHC-01, ZHC-02, 3973, and FC-14. FC-28 single stage high oil oil hydrocracking catalyst. After the FC-28 single-stage high-grade oil hydrocracking catalyst laboratory was finalized, an industrial scale-up test was completed at the Fushun Petrochemical Company's catalyst plant in December 2001. The industrial scale-up of the FC-28 catalyst after 3000 hours of evaluation tests showed that the catalyst's selectivity, stability, and activity of the medium were repeated in the laboratory test results. To test the reaction performance of the FC-28 single-stage high-pressure oil hydrocracking catalyst, the institute conducted a process test on an intermediate hydrocracking tester using an industrially amplified FC-28 catalyst. The test results show that FC-28 catalyst has high temperature sensitivity, can operate within a large range of conversion depth, and has greater flexibility in production operations. At the same time, the middle distillate of FC-28 catalyst has high yield, moderate activity and good isomerization performance. The diesel oil fraction produced has a lower freezing point, higher cetane number, and lower aromatic content and sulfur content. , To meet the needs of China's refining companies to increase production of clean diesel.
