Lubricant hydrogenation technology
Thread Content
Who are the providers of lubricant hydrogenation technologies in China? Compared to foreign countries, what are the advantages and disadvantages? Everyone is welcome to discuss.
I have recently studied lubricant hydrogenation and conducted a preliminary comparison with fuel oil hydrogenation.
Type 3 has a greater degree of hydrogenation than Type 2, lower sulfur content, and a higher viscosity index
Abroad, there are companies such as Shell, Mobil, and Chevron; in China, there are the China Petroleum Research Institute and the Fuzhou Research Institute； Generally speaking, domestic catalysts fall short of foreign ones in terms of liquid yield and product quality. In terms of industrialization, domestic technologies have been widely applied within Sinopec’s system.
The medium-pressure hydrogenation process combined with other techniques is used to produce lubricant base oils with high viscosity indices. This process makes use of the medium-pressure hydrogenation technology developed by the Petroleum Chemistry Research Institute, as well as the RL-1 hydrogenation catalyst. The raw materials used are the reduced third and fourth fraction oils derived from the Karamay No. 0 intermediate paraffin-based crude oil and Shixi crude oil. Through laboratory-scale tests and pilot industrial production, lubricant base oils with viscosity indices of 106 and 98 were obtained, representing increases of 16 and 21 units respectively compared to the existing traditional production methods.
