润滑油抽出油制取橡胶填充油的研究 总被引:2,自引:0,他引:2
以糠醛为溶剂对抚顺石油一厂减五线馏分油溶剂精制的抽出油进行抽提,制备了橡胶填充油.考察了抽提温度和剂油质量比对产物收率和质量的影响.研究结果表明,当剂油质量比一定时,温度升高,产物收率上升,芳烃含量下降;当温度一定时,随着剂油质量比的增大,产物收率上升,而芳烃含量先上升后下降.综合考虑产物质量和收率,本实验范围内较适宜的操作条件为:抽提温度80 ℃,剂油质量比3.0.在此条件下,产物收率为63%,芳烃含量为58.84%. 相似文献

以地沟油为原料,通过高温热裂解得到高酸值85mg(KOH)/g的裂解油,进而通过催化酯化反应降低热裂解油的酸值。讨论了催化剂种类、甲醇用量等因素对酯化率的影响。结果表明,以自制的S2O8^2-/ZrO2固体超强酸作催化剂,甲醇用量(以裂解油质量计)为30%时,酯化效果最好,可以使裂解油酸值降至2mg(KOH)/g。还考察了催化剂的使用寿命,结果表明,催化剂使用到第3次时,酯化率仍可达到84.8%。酯化后裂解油的燃料油性能有所改善。 相似文献

介绍了使用大庆原油掺混50%萨里尔原油试生产润滑油基础油期间,各装置的加工情况并对产品性能指标进行了对比。萨里尔原油酸值小,硫、氮含量较低,属于轻质低硫石蜡基原油,适宜生产润滑油基础油。试生产结果表明:通过优化装置的操作条件,减二线可以生产黏度指数大于90的满足HVIIb等级要求的润滑油基础油,减三线可以生产黏度指数大于80的满足HVIIa等级要求的润滑油基础油。 相似文献

Crude oil imports in China are mainly carried out by state-owned entities with non state-owned entities as compliment. Crude imported by 5 state-owned entities accounts for 90% of the total imports, while non state-owned entities are about given more freedom in using and importing crude. In 2015 only, there were 13 companies granted with access to imported crude oil and 6 were qualified to import rights. Currently, there are 29 non-state-owned companies engaging in crude import business. China oil market is faced with severe challenges. The growth rate of oil demand declined, and dependence upon imported oil increased and reached as high as 61.26% in 2015. Refined oil demand growth also slowed down, and oil refining overcapacity got prominent and completion would become fiercer in future. Overcapacity was about 140 million tons per year in 2015. Consumption ratio of diesel to gasoline went on declining, and the task of product structure adjustment was heavy. China oil market is undergoing great transformation, and institutional mechanism will go ahead, on the basis of centering on orderly release of limitations on crude oil and refined oil import and export, orderly release of competitive business and government pricing of oil/gas downstream links, vigorous resolving of overcapacity, strengthening low-carbon development, and laying a solid foundation for guarantee. 相似文献
