摘要: 采用直馏柴油催化氧化脱硫工艺中试装置,在表观停留时间3~5min、反应温度60℃、氧化催化剂/柴油体积比0.24,反应物料循环量1000L/h和柴油/萃取剂体积比2.5的试验条件下对直馏柴油进行催化氧化脱硫中试研究。精制柴油的产品分析表明:柴油中的主要硫化物二苯并噻吩类被氧化为极性的砜类化合物经萃取脱出,本工艺脱硫效果良好。富集硫化物柴油与催化柴油按1∶10的体积比混合,在模拟兰州石化炼油厂柴油加氢工业装置的操作条件下加氢脱硫,可使混合富硫柴油中的硫含量从2500μg/g降低到800μg/g。富集硫化物柴油可作为催化裂化柴油加氢装置的原料。

Abstract: Adopting the straight run diesel catalytic oxidation desulphurization pilot facility and under the condition that the reactor is the static state one, the apparent time is 3~5 minutes, the reaction temperature is 60℃, the materiel circulation is 1000L/h, the ratio of the TS2 oxidation catalysis to the diesel is 0.24, the ratio of the diesel to the EA1 extractant is 2.5∶1, the pilot test of straightrun diesel is conducted for catalyzingoxidate desulphurization. The production analysis and the qualification indicate that at the aforesaid condition, the main dibenzothiophene sulfide in the diesel are moved out; mixing the sulfide enriched diesel with the catalytic diesel with the volume rate of one to ten and at the simulation conditions of the diesel hydrodesulphurization operation in the Lanzhou refinery, the sulfide in the sulfideenriched diesel declines to 800μg/g from 2500μg/g。The sulfideenriched diesel can be used as the raw material of the catalytic cracking diesel′s hydrogenization facility.
