INDUSTRIAL APPLICATION OF ULTRA-DEEP DESULFURIZATION CATALYST RS-3100 WITH HIGH STABILITY IN DIESEL HYDROGENATION UNIT

Abstract

Abstract: RS-3100 catalyst，a new highly stable ultra-deep hydrodesulfurization catalyst developped by SINOPEC Research Institute of Petroleum Processing,was applied in the 1.2 Mt/a diesel hydrogenation unit of SINOPEC Jiujiang Company for the first time. The unit was successfully started up in April 2020 to process the mixed feedstocks of CGO, LCO and SRGO. The sulfur mass fraction of diesel products is less than 10 μg/g and the mass fraction of polycyclic aromatic hydrocarbons is less than 7%, which can meet the requirements of China Ⅵ vehicle diesel standard. The industrial calibration results showed that RS-3100 catalyst had good activity and stability, and could be used to process 50% inferior feedstocks of secondary oil, and produce China Ⅵ vehicle diesel stably.

Key words: diesel hydrogenation, ultra deep hydrodesulfurization, catalyst, high stability
