Study On The Production Of High Quality Food Grade White Oil From Hydrocracking Bottom Oil By Mid-Pressure Hydrofining

The white oil is one of the important petroleum products, and is applied to thefoodstuff industry, the materia medica production etc. Using the traditionalsulfonation method to produce white oil will pollute the environment. It needs alarge investment and high techniques to produce high quality white oil byhigh-pressure hydrofining, so it is impossible to carry out for a common refinery.Now, by using the mid-pressure hydrofining process and the high activity catalystwe developed, we transform the light Fraction neutral oil HVI H100 fromhydrocracking bottom oil, which is produced by Dushanzi petrochemical company,to the food grade 15# white oil, which meets the national standard GB 4853-94. Thepurpose of using the mid-pressure hydrofining to produce the white oil comes true,and fills up the blank of this field.
