在中型试验装置上对劣质催化裂化柴油 ,在氢分压 6.4MPa条件下进行加氢改质 ,通过应用加氢精制催化剂RN 1和加氢裂化催化剂RT 5的加氢改质工艺可以生产质量收率在 90 %～95%的优质柴油馏分 ,其十六烷值较原料可提高 1 0～ 1 5.7个单位 ,副产品石脑油馏分油的芳烃潜含量在 70 %左右。该技术于 1 998年初在武汉石油化工厂 30 0kt/a加氢改质装置上实现了首次工业应用 ,工业结果与中型结果一致。
In the medium-sized test equipment for low-quality catalytic cracking of diesel, hydrogen partial pressure 6.4MPa under the conditions of hydrogenation modification, through the use of hydrotreating catalyst RN 1 and hydrocracking catalyst RT 5 hydrogenation modification process can produce quality income The rate of 90% to 95% of the high-quality diesel fraction, the cetane number can be increased 10 ~ 5.7 units compared with the raw materials, by-product naphtha distillate aromatic hydrocarbon potential of about 70%. The technology was first industrialized in early 1998 by a 30 kt / a hydrocracking unit at Wuhan Petrochemical Plant, with industrial results consistent with medium-sized results.
