| titleOfInvention | Method and device for producing ethylene and propylene from light hydrocarbon raw material |
| abstract | The invention relates to the field of ethylene and propylene production from light hydrocarbon raw materials, and discloses a method and a device for producing ethylene and propylene from light hydrocarbon raw materials. The method comprises the following steps: (1) cracking light hydrocarbon raw materials to obtain cracked gas; (2) contacting the pyrolysis gas with maleic anhydride, wherein C in the pyrolysis gas 4 Carrying out copolymerization reaction on terminal olefin and maleic anhydride; (3) carrying out gas-liquid separation on the product obtained by the copolymerization reaction to obtain a gas-phase product and a liquid-solid mixture; (4) carrying out gas phase separation on the gas phase product to obtain ethylene, propylene, ethane and propane, and simultaneously obtaining ethane and propane as cycle materials; (5) separating the liquid-solid mixture to obtain C in the pyrolysis gas 4 Copolymers of terminal olefins with maleic anhydride; wherein the pyrolysis gas contains 0.1-10 wt% of C 4 A terminal olefin. Can effectively utilize light hydrocarbon raw materials to produce ethylene and propylene, produce cross-linked copolymer and reduce the energy consumption in the cracking separation process. |
