| titleOfInvention | Method and device for producing ethylene and propylene from n-butane |
| abstract | The invention relates to the field of ethylene and propylene production by using n-butane, and discloses a method and a device for producing ethylene and propylene by using n-butane. The method comprises the following steps: (1) carrying out cracking reaction on n-butane to obtain cracking 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 and a carbon four-fraction, and carrying out hydrogenation reaction on the carbon four-fraction to obtain butane as a circulating material; (5) separating the liquid-solid mixture to obtain a solid product which is a polymer containing maleic anhydride functional groups; wherein the pyrolysis gas contains 4-10 wt% of C 4 A terminal olefin. Can effectively utilize n-butane to produce ethylene and propylene, produce cross-linked copolymer and reduce energy consumption in the cracking separation process. |
