用F-L_2剂络合萃取精制直馏柴油

Refining of Strait Run Diesel Oil by Compound Reagent F-L_2 Complexing Extraction

实验通过选择含有金属离子的复合溶剂(F-L2)络合萃取出直馏柴油中的氮化物,并确定最佳实验条件。结果表明,在剂油质量比为1∶20,反应时间为0.5 min,反应温度为30℃的条件下,经F-L2络合剂络合萃取精制的直馏柴油碱氮脱除率可达88%,油品的色度有明显的改善,油品的收率在96%左右。工艺具有设备简单、精制费用低、操作容易、无污染等特点,已在一些小型炼油厂实现工业化。

A suitable compound solvent （F- L2 ） containing a kind of metallic ion was selected to remove the nitrogen compounds by complexing extraction in strait mn diesel oil At the ,same time the optimal experimental conditions were determined, The results show that the best operational conditions of the technology are that the mass ratio of agent to diesel is 1 ： 20, the reaction time is 0.5 min and reaction temperature is 30 ℃. The extraction rate of basic nitrogen by the reagent F - L2 is 88%. The color has been improved obviously refining expenditure, The refined oil recovery is about 96%. The processing has some characters such as simple equipment, low easy to control and no pollution. It has been realized industrialization in rome small refineries.
