以中海油环烷基常二线和减三线馏分油及其混合油作为原料，通过高压加氢处理、糠醛精制组合工艺制备变压器油和环保橡胶油。结果表明，常二线馏分油单独进料，通过单段高压加氢处理工艺可得到满足GB 2536—2011的变压器油。减三线馏分油单独进料，通过单段高压加氢处理工艺可直接生产C_A为10%的环保橡胶油。2种馏分油混合进料，通过高压加氢处理和糠醛精制组合工艺可生产C_A超过25%的高芳环保橡胶油，生产的变压器油C_A较高，与深度精制石蜡基变压器油调和可得到满足GB 2536—2011的变压器油。2种馏分油混合进料可避免因原料切换产生过渡油，充分释放加工能力，提高装置利用率。

The transformer oil and environmental friendly oil both with high C_A 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 C_A value of 10%.The high aromatic hydrocarbons-containing environmental friendly rubber oil with a C_A 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 C_A 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.
