Method and system for preparing jet fuel from Fischer-Tropsch synthesis intermediate product

The invention relates to a method for deep processing of a Fischer-Tropsch synthesis intermediate product to obtain jet fuel (or aviation kerosene) and a system for implementing the same. Specifically, the Fischer-Tropsch synthesis liquefied gas and naphtha are subjected to reforming and/or aromatization and alkylation to obtain the alkyl aromatic hydrocarbon component, so that the defect that the Fischer-Tropsch synthesis oil is single in composition structure is overcome, and meanwhile, the yield of the aviation kerosene component is greatly improved. According to the method, high-quality aviation kerosene can be produced, and the aviation kerosene has the advantages of being free of sulfur or extremely low in sulfur content, high in smoke point and heat value and the like and can be used for preparing high-quality super-clean aviation fuel. 本发明涉及由费托合成中间产品深度加工得到喷气燃料(或航空煤油)的方法和实施其的系统。具体而言，本发明将费托合成液化气及石脑油通过重整和/或芳构化和烷基化得到烷基芳烃组分，弥补了费托合成油组成结构单一的不足，同时大幅度提高航煤组分收率。根据本发明的方法能够生产高品质航空煤油，其具有无硫、或极低硫含量，高烟点和热值等优点，可用于制备优质的
