以加氢改质柴油掺炼绥中减一线为原料,考察采用临氢降凝-补充精制-精密分馏工艺制备满足行业标准NB/SH/T 0913—2015轻质白油(Ⅰ)指标要求和国标GB 2536 T-40℃变压器油指标要求产品的可行性。结果表明,在反应压力为15 MPa、氢油体积比为500、空速为1.0/0.5 h^-1的条件下,以加氢柴油为原料,当反应温度为T₁/T₂时,可生产满足轻质白油(Ⅰ)、变压器油指标要求的产品;以绥中减一线为原料,无法生产满足轻质白油(Ⅰ)、变压器油指标要求的产品;以加氢柴油掺炼10%减一线为原料,在反应温度T₁+60/T₂+60℃时,可生产满足轻质白油(Ⅰ)、变压器油指标要求的产品。

This study evaluates the feasibility which preparing NB/SH/T 0913—2015 light white oil(I) and GB2536 T-40℃ transformer oil through hydrodewaxing-supplementary refining-precision fractionation process with hydrogenated diesel oil and first-line oil from vacuum distillation tower of Suizhong crude oil as feedstocks.The results show that the light white oil(I) and transformer oil products meeting the requirements can be produced when the reaction pressure is 15 MPa,the volume ratio of hydrogen to oil is 500,and the space velocity is 1.0/0.5 h^-1,the hydrogenated diesel oil is used as feedstock and the reaction temperature is T₁/T₂.If first-line oil from vacuum distillation tower of Suizhong crude oil is used as feedstock,light white oil and transformer oil produced cannot meet the requirements of the standards.Qualified light white oil and transformer oil can be produced when the reaction temperature is T₁+60/T₂+60℃,and hydrogenated diesel oil blending with10% of first-line oil from vacuum distillation tower is used as feedstock.
