Abstract:

Hydrogenation cracking tail oil is of excellent performance, with high saturated hydrocarbon content, low sulfer and nitrogen content, it can be ethane cracking substance, also good quality basic oil raw material of lubricating oil, it can also be used to produce transformer oil, combustion engine oil and hydraulic oil etc., meanwhile, the by product of diesel can be obtained. Hydrogenation cracking tail oil from Liaoyang petrochemical Corp. is researched in Lab, the utilization of the hydrogenation cracking tail oil as basic oil of lubricating oil is investigated through the technique of vacuum distillation, solvent dewax and replenishment refinement. Research indicates that 15.3% HVI100 basic oil recovery, 35.4% HVI150 basic oil, 20.4% HVI 400 basic oil, diesel and transformer oil, can be obtained through hydrogenation cracking tail oil.

Key words: hydrogenation cracking tail oil, narrow fraction, high viscosity index, basic oil, comprehensive utilization
