Based on investigation of the properties of the catalyst carrier, the impregnated solution and the preparation method, etc., Sinopec Research Institute of Petroleum Processing(RIPP) has developed the RS-2100 catalyst, a new, high-active diesel ultra-depth hydrodesulfurization catalyst. The high-active ULSD RS-2100 catalyst features 15% higher activity along with 15% lower packing density compared to similar ULSD catalysts. This paper introduces the commercial application of RS-2100 catalyst in diesel hydrot...
