Abstract: The coking kerosene distillate was hydrotreated to produce the feedstock for the liquid paraffin production by Fushun Research Institute of Petroleum Processing (FRIPP) and its industrial application was introduced. The pilot test results showed that when typical coking kerosene fractions were hydrotreated at 5.5 MPa, 320 ℃, LHSV 1.5 h-1, the volume ratio of hydrogen/oil 400 or at 4.5 MPa, 320 C, LHSV 1.0 h-1 and the volume ratio of hydrogen/oil 400 , the content of sulfur and nitrogen in product can be reduced to less than 1.0 ?g/g, which meets the quality requirements of liquid paraffin feedstock. The industrial application proved the feasibility of producing liquid paraffin feedstock by hydrogenation of coking kerosene distillate. It is concluded that the hydrogenation technology can provide a new technical route to supply liquid paraffin feedstock with increasing the added value of coking distillate oil.

Key words: coking kerosene, hydrogenation, liquid paraffin feedstock
