【摘要】：在优化的工艺条件下对宝明页岩油进行溶剂抽提精制,考察溶剂的选择、抽提温度、剂油质量比、沉降时间对页岩油精制效果的影响。结果表明:选用N,N-二甲基甲酰胺为溶剂,在抽提温度为60℃、剂油质量比为0.5、反应时间为10min、沉降时间为30min的条件下,抽余油收率为72%,抽出油收率为26%,所得抽余油中不饱和烃、硫、氮、氧含量,残炭明显降低,可作为加氢精制原料,其氢气消耗量比原料直接加氢降低约52.48%,抽出油中小于420℃组分满足4号燃料油标准,大于420℃组分可制备90号重交通道路沥青。
[Abstract]:The effects of solvent selection, extraction temperature, ratio of solvent to oil quality and settling time on the refining effect of Baoming shale oil were investigated under the optimized technological conditions. The results showed that the yield of residual oil was 72 and the yield of extracted oil was 26 under the conditions of extraction temperature of 60 鈩，
