Abstract: 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 H2/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 ratio 40(v). The1000 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.
