Abstract

Tests of diesel fuel hydrotreating catalysts have been carried out, which have passed the reactivation procedure according to the technology developed by JSC «all-Russian Oil Refining Research institute». The efficiency of the reactivation technology was evaluated of catalysts for hydrotreating diesel fuels and vacuum gas oil. Based on a comprehensive analysis of the physico-chemical and catalytic properties of regenerated, reactivated and fresh hydrotreating catalysts, the dynamics of changes in the operating characteristics of catalysts is investigated. The results obtained at the pilot plant were confirmed during an industrial run at the L-24/7 hydrotreating plant of JSC «Syzran Oil Refinery». The presented results demonstrate the high activity and stability of reactivated catalytic systems in the process of hydrotreating diesel fuel and vacuum gas oil, in comparison with the results of operation of fresh catalysts of similar brands. I confirm the results of monitoring the operation of reactivated catalytic systems at an industrial technological installation.

加氢处理催化剂的再活化效率评价

已经进行了柴油加氢处理催化剂的测试，该催化剂已根据JSC“全俄炼油研究所”开发的技术通过了再激活程序。对加氢处理柴油和真空瓦斯油催化剂的再活化技术进行了评价。在综合分析再生、再活化和新鲜加氢处理催化剂的理化性质和催化性能的基础上，研究了催化剂工作特性变化的动态规律。在中试装置中获得的结果在JSC“Syzran炼油厂”L-24/7加氢处理厂的工业运行中得到了证实。结果表明，再活化催化体系在柴油加氢处理和真空瓦斯油加氢处理过程中具有较高的活性和稳定性，并与同类品牌新鲜催化剂的运行结果进行了比较。我确认在一个工业技术装置中监测再激活催化系统运行的结果。
