重整催化剂在哈萨克斯坦炼油厂的应用

中国石化石油化工科学研究院研制的SR-1000催化剂在“一带一路” 哈萨克斯坦奇姆肯特PKOP炼油厂1.0 Mt/a半再生催化重整装置上进行了工业应用。SR-1000催化剂运转6个月时的标定结果表明,在设计满负荷进料(125 t/h)、反应器加权平均反应温度（WABT）不大于485 ℃的条件下,稳定汽油RON为96.3,收率比协议值高0.2百分点。在运转时间基本相当、原料的环烷烃与芳烃质量分数之和高1.49百分点、质量空速高21%的情况下,SR-1000催化剂的活性及选择性均优于国外对比剂R。SR-1000重整催化剂开工方法简单,不仅可以显著缩短开工时间,而且安全、环保,可以降低开工风险。以上结果表明,SR-1000催化剂用于生产高辛烷值汽油调合组分,具有良好的活性、选择性和稳定性,可以满足半再生催化重整装置在高苛刻度下长周期稳定运转的需要。

APPLICATION OF CATALYTIC REFORMING CATALYST SR-1000 IN KAZAKHSTAN REFINERY

The SR-1000 catalyst developed by SINOPEC Research Institute of Petroleum Processing was applied in the 1.0 Mt/a semi-regenerative reforming unit of PKOP Refinery in Shimkent,Kazakhstan of "one Belt and one Road ". The calibration results after 6 months operation showed that the RON of stable gasoline was 96.3 and the yield was 0.2 percentage point higher than that of the protocol under the conditions of the designed full load of 125 t/h and the WABT less than 485 ℃. Compared with the foreign catalyst R, the activity and selectivity of SR-1000 catalyst were better under the conditions of basically the same operating time and the feed with the cycloalkanes and aromatics content of raw materials 1.49% higher, and the WHSV of 21% higher. The starting-up method of SR-1000 catalyst is simple, which can not only significantly shorten the starting time, but also be safe and environmentally friendly, and can reduce the starting-up risk. The results of industrial application showed that SR-1000 catalyst has good activity,selectivity and stability in the production of high octane gasoline blending components,which can meet the needs of long-term stable operation of reforming unit under high stringent conditions.
