摘要:
催化裂化油浆含有重芳烃和饱和烃,以及少量胶质沥青质,可以通过溶剂抽提和馏分切割分离后分别加以利用。提出了油浆减压切割-溶剂抽提(方案1)和溶剂抽提-减压切割(方案2)两种加工工艺方案,对比考察了工艺条件以及产品性质。在5.586 kPa真空度下,减压切割胶质、沥青质重馏分的温度均为355 ℃。方案1抽提条件:剂油比1.8,抽提搅拌时间20 min,抽提温度70 ℃; 其抽余油、芳烃馏分、重馏分收率分别为26.94%、42.86%、30.20%; 抽余油中饱和烃含量82.50%,芳烃馏分中芳烃含量86.62%。方案2抽提条件:剂油比2.5,抽提时间30 min,抽提温度80 ℃,其抽余油、芳烃馏分、重馏分收率分别为39.10%、32.17%、28.73%; 抽余油中饱和烃含量61.14%,芳烃馏分中芳烃含量85.11%。经比较,方案1优于方案2。
Abstract:
The Fluid Catalytic Cracking Slurry contains heavy aromatics,satisfied hydrocarbon and a small amount of gum and bituminous, which could be used separately by solvent extraction and fraction cutting. This study putforward two process technologies which were vacuum cutting-solvent extraction(scheme 1)and solvent extraction-vacuum cutting(scheme 2)of slurry and conducteda comparative study of technology conditions and product properties. The temperature of cutting gum and bituminous are both 355 ℃ under the vacuum degree of 5.586 kPa. The extractive conditions of scheme 1 are as follows: solvent to oil 1.8, extractive stirring time 20 min, extractive temperature 70 ℃; the yield of raffinate oil,aromatic fraction,heavy fraction are 26.94%,42.86%,30.20% respectively; the content of satisfied hydrocarbon in raffinate oil were 82.50% and the content of aromatic hydrocarbon in raffinate oil are 86.62%. The extractive conditions of scheme 2 are as follows: solventto oil 2.5, extractive stirring time 30 min, extractive temperature 80 ℃; the yield of raffinate oil,aromatic fraction,heavy fraction were 39.10%,32.17%,28.73% respectively; the content of satisfied hydrocarbon in raffinate oil are 61.14% and the content of aromatic hydrocarbon in raffinate oilare 85.11%.
