Study on the Modification of FCC Diesel Quality by Non—Hydrofining Method

In this article,the FCC diesel fuel is chemically treated with GZ reagent.The existent gum,insolubles after oxidation,and iodine munber are greatly reduced after chermical treatment.This method has a good effect and is simple.This method is characterized by high recovery rate of fuel(>99.7?and low cost.The property of the mixture of chemically treated diesel fuel with straight-run diesel fuel can meet the requirements of national standard GB252-2000.The color and oxidation stability of the mixed fuel after having been stored for three months were still lower than the values specified in the national standard.

催化柴油化学精制工业应用

采用GZ试剂对三催化柴油进行化学精制的工业应用表明,该种化学精制方法精制效果好、工艺简单,精制后柴油氧化沉渣大幅度下降,柴油收率高(>99.7%)、处理成本低。将精制后的催化柴油与常压直馏柴油、加氢柴油进行调合,调合后成品柴油的各项指标均达到GB252-2000柴油出厂标准。对化学精制处理调合后的成品柴油进行储存实验,储存3个月后色度及氧化沉渣均符合国家标准。
