摘要
以中国石油青海油田格尔木炼油厂(格尔木炼油厂)常一线油为原料,采用管式固定床选择性液相加氢(FITS)工艺,进行了生产喷气燃料的研究,考察了反应压力、反应温度、空速、氢油比等条件对FITS加氢效果的影响。结果表明:在反应压力4.0MPa、反应温度300℃、体积空速8.0h-1、氢油体积比40的条件下可以生产出硫质量分数小于10μg/g的清洁喷气燃料产品;通过1 000h连续运转,催化剂活性保持平稳,脱硫率稳定在87%左右、脱硫醇率稳定在85%左右、脱酸率稳定在80%左右,表明喷气燃料FITS工艺能够实现长周期运转的要求;通过设计核算,该装置在建设投资、占地面积、加工能耗等方面均低于同等规模滴流床加氢装置,具有良好的工业应用前景。
The clean jet fuel production by FITS technology using No.1 side-stream of atmospheric distillation of Geermu refinery as feed was studied.The effects of reaction pressure,temperature,space velocity and H 2 oil ratio on FITS results were investigated.The test showed that the clean jet fuel with total sulfur content less than 10μg g can be produced at conditions of 4.0 MPa,300℃,LHSV 8.0 h-1,and hydrogen to oil volume ratio 40.The 1 000 hours continuous test indicated the excellent stability of the catalyst activity,the desulfurization rate keeps about 85%,mercapten removal about 87%and deacidification rate about 80%.It shows that the FITS process can realize the long-cycle production of clean jet fuel.The technical and economic assessment demonstrates that the FITS device is lower in construction investment,floor area and energy consumption than that of the same size trickle bed reactor,and has a good prospect of industrial application.
