| titleOfInvention | Reaction unit for catalytic conversion of methanol to low-carbon olefins |
| abstract | The invention relates to a reaction unit for catalytic conversion of methanol to low-carbon olefins, mainly solving the problem of low yield of low-carbon olefins in the prior art. The reaction unit disclosed herein mainly comprises a gas-solid distribution zone 19, a downer reaction zone 18, a riser reaction zone 11, a disengager 16, and a regenerator 3, wherein the bottom of the riser reaction zone 11 is provided with a rising section 10, the side part of the rising section 10 is provided with a catalyst inlet which is connected with a regeneration inclined pipe 7, the riser reaction 11 is connected with the gas-solid distribution zone 19, the lower portion of the gas-solid distribution zone 19 is connected with the downer reaction zone 18, the outlet of the downer reaction zone 18 is connected with a rough-cut cyclone 17, the gas-phase outlet of the rough-cut cyclone 17 is connected with the inlet of a cyclone separator 2 in the disengager 16, the lower portion of the disengager 16 is provided with a stripping zone 4, the bottom of the stripping zone 4 is connected with the regenerator 3 through a regeneration standpipe 6, and the regenerator 3 is connected with a regeneration inclined pipe 7. The reaction unit disclosed herein well solves the problems and can be used in the industrial production of low-carbon olefins. |
