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.
