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

  • entering composite heating stove be warming up to 450-570 DEG C after efficient anti-coking charging vaporizer 100-109 DEG C of gasified through impurity pretreatment high olefin content lighter hydrocarbons, then under circulation returns the drive of carrier gas, solid bed double-reactor is entered from top to bottom, aromatization is carried out under the effect of catalyzer, temperature of reaction 500 DEG C-600 DEG C, pressure 0-0.4MPa, air speed 0.4-0.8h -1;

    Described high olefin content lighter hydrocarbons are oil liquefied gas, civil liquefied gas, cracking c_5 or the two mixture arbitrarily;

    Described catalyzer is the marque that Shandong Qiwangda Group Haizhong Chemical Industry Technology Co., Ltd. produces is the aromatizing catalyst for light hydrocarbon of DLP.
