The refining of distillate fuel oils by acid-alkali washing and fractional distillation has been presented and the improvement of function of the product to use as diesel oils have been studied.

本文主要介绍了洗油的精制-酸、碱洗涤、精馏,以及对由洗油制得的产品-柴油性能的改进,进行了研究.

A simple solution (or its desiccant) of polyethylene wax (PEW),PEWA is used as a fluidity improver for blended diesel-fuels. Its effect of solidification point depression when used in combination with ECA 5920 is investigated. The blended diesel fuels dosaged with PEWA or PEWA+ECA 5920meet the requirements of diesel fuel specification. Furthermore,PEWA is more resistant to wax lamination.

本文介绍了聚乙烯蜡(PEW)经研制得到的一种溶液或干剂,PEWA作为调合轻柴油流动性改进剂,以及它与ECA5920R合后加到调合柴油中的降凝效果。加剂后的调合轻柴油性能已达到柴油指标要求,同时该剂对柴油还有较好的抗蜡分层的作用。

Putting forward a new kind of method-microwave irradiation in the process of the removal of acid from Jinxi straight-run diesel oil, the optimum conditions of refining process were investigated. The ratio of solvent-to-oil is 0.25∶1, the pressure is 0.04 MPa, the radiant time is 5 min under the constant pressure, microwave power is 375 W. When the resting time is up to 20 min, the acidity will be reduced from 89.5 mgKOH/100mL to 3.78 mgKOH/100mL, and no effect on the quality of the diesel oil, thus it is good...

Putting forward a new kind of method-microwave irradiation in the process of the removal of acid from Jinxi straight-run diesel oil, the optimum conditions of refining process were investigated. The ratio of solvent-to-oil is 0.25∶1, the pressure is 0.04 MPa, the radiant time is 5 min under the constant pressure, microwave power is 375 W. When the resting time is up to 20 min, the acidity will be reduced from 89.5 mgKOH/100mL to 3.78 mgKOH/100mL, and no effect on the quality of the diesel oil, thus it is good enough to meet the best specification of GB. The recovery can reach 99.6%. The whole process of the microwave refinement spends less time, consumes less electricity, and is propitious to the environment.

用微波辐射的方法对锦西炼油厂生产的直馏柴油进行了脱酸精制试验 ,并考察了精制过程中的最佳试验条件。当剂油体积比为 0 .2 5∶1、压力为 0 .0 4MPa、恒压辐射时间为 5min、微波功率为375W、静置时间为 2 0min时 ,可将柴油的酸度由 89.5mgKOH/ 10 0ml降至 3.78mgKOH/ 10 0ml,达到国家规定优质柴油质量标准 (小于 5mgKOH/ 10 0ml) ,且精制过程对柴油性能无影响 ,回收率达到 99.6 %。该精制过程节省时间、耗电量小 ,有利于环境保护。
