Where is Hydrorefining used?
Lube Oil Hydrorefining
The target of Axens' Hydrorefining technology is the production of a wide choice of suitable lubricant base stocks from a variety of crude sources. Very similar to the hydrocracking process regarding operating conditions, it uses a special amorphous catalyst having a dual function (hydrotreating and cracking). The production of lube oils with Viscosity Index (VI) values between 95 and 135 is associated with a conversion to lighter fractions between 20 and 60 wt%.
