A hydrogenation catalyst and its preparation method developed by Sinopec Fushun Petrochemical Research Institute for maximum production of diesel oil have recently won the 15th China Patent Excellence Patent Award. The overall performance of the FC-14 hydrogenation catalyst successfully developed using this technology has reached the international advanced level, filling the gap of the largest domestic special-purpose catalyst for the production of large-scale single-stage full-cycle hydrocracking units of high-quality diesel, opening up the improvement of diesel fuel for China's refining industry New ways to produce more diesel fuel blending components that meet Euro V standards.
FC-14 hydrogenation catalyst uses a compound of special modified molecular sieve and amorphous silicon aluminum as a cracking component. By optimizing the catalyst formulation and preparation process, it can meet the needs of producing high-quality middle distillate oil, especially high-quality low-condensation diesel. Researchers have developed a number of new technologies and applied for patent protection for innovative technical content such as special modified molecular sieve products, catalyst composition, related process flow, and have obtained 5 patent authorizations.
The FDC complete set of technology developed with FC-14 hydrogenation catalyst as the core integrates many advanced technologies in the field of hydrocracking in the design of the device, which can keep the traditional single-stage hydrocracking process simple, large space velocity and high diesel yield 1. The characteristics of low chemical hydrogen consumption and low equipment investment. It also has the advantages of strong adaptability to raw oil, long catalyst operating cycle and low energy consumption. It can meet the needs of refining and chemical enterprises for producing high-quality diesel. Provide technical support for the upgrading of diesel quality and the production of low-condensation diesel products. The catalyst has been applied in Jinling Petrochemical, Hainan Refining and Chemical, Liaoyang Petrochemical and Jinzhou Petrochemical, and many new large-scale hydrocracking units, which can produce high-value products such as low-condensation clean diesel.
By the end of 2014, China's automotive diesel will implement the National IV emission standard (diesel sulfur content <50g / g); by the end of 2017, China's automotive diesel will implement the National V emission standard (diesel sulfur content <10g / g). Chemical companies have put forward higher requirements.
