Abstract: The transformer oil and environmental friendly oil both with high CA value can be produced via high pressure hydrogenation combining with furfural refining process by using CNOOC-made naphthenic atmospheric 2# line and vacuum 3# line distillates as raw materials.It is found from the research results that atmospheric 2# line distillate alone can be processed by single stage high pressure hydrogenation method into transformer oil than can meet GB 2536-2011,vacuum 3# line distillate alone can be processed by single stage high pressure hydrogenation method to produce environmental friendly rubber oil with a CA value of 10%.The high aromatic hydrocarbons-containing environmental friendly rubber oil with a CA value more than 25% can be produced by the combined process with hydrogenation and furfural refining,using mixed atmospheric 2# line and vacuum 3# line distillate as raw materials.The combined process with mixed distillates fed can produce transformer oil with high CA value,which can be blended with deep refining paraffin-based transformer oil to meet GB 2536-2011 standard.The mixed distillate feed can avoid the production of transition oil caused by raw material switching,utilize fully the processing capacity and improve the utilization rate of facility.
