Embodiment 1～6

[0032] In this example, two kinds of straight-run diesel oils A and B are used as raw materials, and the catalysts are all commercial catalysts developed by Fushun Petrochemical Research Institute. The hydroprocessing reaction zone and supplementary hydrofining reaction zone are filled with FF-46 hydroprocessing catalyst , The hydrocracking reaction zone is filled with FC-50 catalyst. The specific operation process adopted is shown in the appendix figure 1 . The embodiment adopts the form of two reactors connected in series, and the hydrotreating reaction zone and the hydrocracking reaction zone are in one reactor. The properties of the feedstock oil are shown in Table 1, the basic properties of the catalyst are shown in Table 2, the feedstock oil of Examples 1 to 3 is straight-run diesel oil A, and its process operating conditions and results are shown in Tables 3 to 4; the feedstock oils of Examples 4 to 6 are Straight-run diesel oil B, its process operating conditions and...

Abstract

The invention discloses a method for producing jet fuel by straight-run diesel oil. The method comprises the following steps: (1) mixing a straight-run diesel oil raw material with hydrogen gas; enabling a mixture to enter a hydrogenation treatment reaction region; carrying out hydrogenation and desulfurization reaction and hydrogenation and denitrification reaction under a condition of relatively low temperature and / or a large volume space velocity; (2) enabling refined straight-run diesel oil obtained by step (1) to enter a hydrocracking reaction region and be in contact with a hydrocracking catalyst; carrying out hydrocracking reaction; (3) enabling a full-fraction hydrocracking product obtained by step (2) into a hydrogenation refining reaction region and carrying out aromatic hydrogenation saturation reaction; (4) enabling a refined full-fraction product obtained by step (3) to enter a separation and fractionation system, so as to obtain naphtha and jet fuel products and the like. Compared with the prior art, the method disclosed by the invention can be used for producing the straight-run diesel oil into the jet fuel at maximum and the additional value of the product is improved.

Description

technical field [0001] The invention relates to a production method of jet fuel, in particular to a production method of producing high-quality jet fuel through straight-run diesel oil. Background technique [0002] With the continuous expansion of the international air transport industry, the global demand for jet fuel is increasing year by year, with an annual growth rate of about 5.0%, far higher than the annual growth rate of gasoline and diesel of 1.0% to 1.5%, which has greatly driven the global The demand for high-quality jet fuel products in the oil market has also promoted the rapid development of jet fuel production technology in the oil refining industry. Worldwide, the existing jet fuel production technologies are mainly straight-run jet fuel distillate hydrotreating technology and hydrocracking technology. Compared with diesel or gasoline products, jet fuel products have more advantages in profit, which greatly promotes major oil refineries. Enterprises increas...
