1. the method utilizing low olefin-content lighter hydrocarbons to produce aromatic hydrocarbons, it is characterized in that, comprise the steps:

  • that low olefin-content lighter hydrocarbons are after impurity pretreatment, after the gasification of charging vaporizer, enter composite heating stove be warming up to 570 DEG C, then enter fixed bed double-reactor from top to bottom, under the effect of catalyzer, carry out aromatization, temperature of reaction 500 DEG C-600 DEG C, pressure 0.1-0.4MPa, air speed 0.4-0.8h -1;

    Described low olefin-content lighter hydrocarbons are condensate oils, and its composition according to per-cent is;

    butane 5.25%, C 5 alkane 37.17%, C 5~ C 8alkane 57.58%;

    Described catalyzer is the marque that Shandong Qiwangda Group Haizhong Chemical Industry Technology Co., Ltd. produces is the aromatized catalyst of DLP;

    Described composite heating stove and accessory has carbon steel-organic non-metal lining.
