Method for preparing low-carbon olefin and coproducing aromatic hydrocarbon by using methanol and/or dimethyl ether |
| abstract |
The application discloses a method for preparing low-carbon olefin and coproducing aromatic hydrocarbon by using methanol and/or dimethyl ether, which comprises the following steps: a) the method comprises the following steps that a feed gas containing methanol and/or dimethyl ether is in contact reaction with a bifunctional catalyst in a hydrogen reaction system in the presence of hydrogen to generate a mixed material flow I containing low-carbon olefin, light components below C4 and heavy components above C4; b) separating the mixed material flow I obtained in the step a) by a separation system, and then enabling the light component and the heavy component to enter an aromatization reaction system to carry out aromatization reaction to generate a mixed material flow II containing the light aromatic hydrocarbon component and hydrogen; c) recycling the hydrogen generated in the step b) to the hydrogen reaction system for use. The method relates the high-pressure hydrogenation reaction and the light hydrocarbon aromatization reaction, so that the aromatic hydrocarbon with high added value is co-produced while the low-carbon olefin is produced, and the byproduct hydrogen is used by a hydrogenation reaction system, thereby solving the problem of hydrogen source in the hydrogenation reaction system and greatly increasing the economical efficiency of the process. |
