摘要： 针对催化柴油安定性差问题,对其不安定组分和改善其安定性的方法进行了研究,结合炼油厂的生产实际,利用复合溶剂对催化柴油萃取精制的生产工艺进行了开发和试验。用HD复合溶剂对催化裂化柴油进行精制后,精制油的催速储存安定性沉渣和颜色均达到了优级轻柴油的标准,在剂油比为1:500—50:500,精制油的收率为99%以上,老化沉渣<2.5·10-2mg/ml,老化色号不大于3.5,实际胶质的降低率达到了60.1%,氧化沉渣降低77.6%,脱硫率19.8%,脱氮率20.3%。

Abstract: The stable components of catalytic diesel fuel and the methods of improving its stability have been studied. The pro-duction process of extracting and refining the catalytic diesel fuel by complex solvent has been tested. Results indicate that the yield of refined diesel is over 99% when the ratio of solvent tooil is 1:500-50:500. After aging, the amount of sediments is less than 2.5mg/100ml and the color of the refined oil is not more than 3.5. The gum and oxidized sediments are reduced by 60.1% and 77.6% respectively. Also the percentage of remov-ing nitrogen and sulfur is 19.8% and 20.3%.
Key words: catalyst, diesel, solvent, refining, technology process
