【摘要】：在優(yōu)化的工藝條件下對寶明頁巖油進(jìn)行溶劑抽提精制,考察溶劑的選擇、抽提溫度、劑油質(zhì)量比、沉降時(shí)間對頁巖油精制效果的影響。結(jié)果表明:選用N,N-二甲基甲酰胺為溶劑,在抽提溫度為60℃、劑油質(zhì)量比為0.5、反應(yīng)時(shí)間為10min、沉降時(shí)間為30min的條件下,抽余油收率為72%,抽出油收率為26%,所得抽余油中不飽和烴、硫、氮、氧含量,殘?zhí)棵黠@降低,可作為加氫精制原料,其氫氣消耗量比原料直接加氫降低約52.48%,抽出油中小于420℃組分滿足4號燃料油標(biāo)準(zhǔn),大于420℃組分可制備90號重交通道路瀝青。
[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，
