摘要: 针对柴油加氢脱硫技术设备投资和操作费用高,柴油H2O2氧化脱硫技术又存在氧化剂价格高、柴油收率低和有含硫污水排放等技术经济问题,开发了一种新型直馏柴油催化氧化脱硫方法,在此为其中试试验研究。直馏柴油催化氧化脱硫中试装置由催化氧化反应、催化剂再生回收、萃取脱硫与萃取剂回收等四个单元组成;反应器为静态混合反应器;在建立的中试装置上对直馏柴油催化氧化脱硫操作条件进行了优选实验:在表观停留时间3~5min、反应温度60℃、反应物料循环量1000L/h、氧化催化剂/柴油体积比为0.24和柴油/萃取剂体积比为2.5的最佳实验操作条件下,成品柴油的硫含量从2273μg/g降到106μg/g,柴油硫含量符合欧洲Ⅱ类柴油标准(≤300μg/g),脱硫率达到95.34%,柴油收率为97.23%。

Abstract: Aiming at the technical and economical problems in diesel hydrodesulphurization which includes high equipment investment and operation cost, and the problems in hydro peroxide oxidation desulphurization method such as expensive oxidant, low diesel yield and sulfur containing polluted water emission, a new catalytic oxidation desulphurization method of straightrun diesel is developed to conduct pilot test research. The pilot catalyticoxidation desulphurization facility of the straightrun diesel includes oxidation unit, recover unit of the TS2 oxidation catalysis, extraction and the EA1 extractant recover unit;the reactor is the static mixingreactor;under the most desirable conditions that the apparent residence time is 3~5 minutes, the reaction temperature is 60℃, the materiel circulation is 1000L/h, the proportion of the TS2 oxidation catalysis to the diesel is 0.24, the proportion of the diesel to the EA1 extractant is 2.5∶1, the sulfur in the turnoff diesel can drop from 2273μg/g to the 106μg/g. The sulfur content in the desulfurized diesel accords with the diesel criterion of EuropeⅡ(≤300μg/g), the desulphurization rate of the straightrun diesel reaches 95.34% and the refined diesel yield 97.23%.
