Abstract Many large diesel vehicles and diesel fuel the main driving force, with power, and the advantages of cheap, is the largest of China's consumption of petroleum products. As environmental awareness increased, and on diesel products increasingly stringent quality requirements, for which China has developed new standards for 2000 diesel GB252-2000, for motor vehicle diesel sulfur content, color, sediment and other references Of a higher demand. This paper discusses the application of non-hydrogenation FS - Trap complex RFCC diesel refining process. Fushun Petrochemical Corporation of raw materials from the production of heavy oil catalytic cracking plant diesel (55%-doped vacuum residue), Jing Jing FS preparation for FS01 complexing agents and trapping agent. FS Act refined diesel RFCC higher yield of diesel oil, up to . Basic nitrogen removal rate of percent, the actual rate of glial lower, the total insoluble reduced to mg/100mL. After the catalytic cracking of refined diesel fuel does not contain water-soluble acid-base; mercaptan sulfur content by μg • g-1 down to 0μg • g-1; refined diesel colority RFCC , oxidative stability for the total insoluble mg/100mL, to meet national quality standards GB252-2000 requirements. In this paper, the design of the production capacity of 200,000 tons of non-RFCC diesel hydrotreating unit, as well as the process principle, major equipment selection, size of the calculation and description of technical parameters. The experimental results show that: the technology is most cost far less than the hydrogenation is the hydrogenation capacity of non-diesel refinery to upgrade the quality of an effective way.打字好辛苦。。。。。
