The performance evaluation of denitrifier LCH-28 and its application in the production of lube base oil

Denitrogenation experiments have been made for the different kinds of lube base oil with denitrifier LCH-28 and WSQ-2,then the denitrogenation oil were treated by the white-clay.The results show that denitrifier LCH-28 is better than WSQ-2 in the aspect of sulfur retaining and denitrogenation.On the basis of the success in the laboratory,the denitrifier LCH-28 has been industrialized in the No.1 Petroleum Refinery Factory in Fushun to produce the lube base oil,the results show that the optimum weight ratio of denitrifier to oil is 1∶(430～500) and the appropriate weight percent of clay is 1.0% for the second vacuum side furfural refined oil;the optimum weight ratio of denitrifier to oil is 1∶320 and the appropriate weight percent of white-clay is 1.45% for the third vacuum side furfural refined oil.The yield of refined oil is increased from 96%～98% to 99.3%.The profit is remarkable.
