摘要： The present application discloses a regeneration device, a device for preparing low-carbon olefins, and a use thereof. The regeneration device includes a first regenerator and a second regenerator; a first activation zone of the first regenerator is connected to the second regenerator through a pipeline, such that a catalyst in the first activation zone is able to be delivered to the second regenerator; and the second regenerator is connected to a gas-solid separation zone of the first regenerator through a pipeline, such that a catalyst in the second regenerator is able to be delivered to the gas-solid separation zone. The regeneration device can adjust the coke content, coke content distribution, and coke species in a dimethyl ether/methanol to olefins (DMTO) catalyst to control an operation window of the DMTO catalyst, which improves the selectivity for low-carbon olefins and the atomic economy of a methanol-to-olefins (MTO) technology.

摘要： Disclosed is a method for partially regenerating a catalyst for methanol and/or dimethyl ether-to-olefin. The method comprises: introducing a mixed gas into a regenerated region containing a catalyst to be regenerated, and subjecting same to a partial regeneration reaction to obtain a regenerated catalyst, wherein the mixed gas contains water vapor and air; and in the regenerated catalyst, the coke content of at least part of the regenerated catalyst is greater than 1%. The method utilizes the coupling of a mixed gas of water vapor and air to activate a deactivated catalyst, selectively eliminate part of a coke deposit in the catalyst to be regenerated, and obtain a partially regenerated catalyst for methanol-to-olefin. Another aspect of the present invention is that further provided is a method for methanol and/or dimethyl ether-to-olefin by using the partially regenerated catalyst for methanol-to-olefin regenerated by means of the method.

摘要： The present application discloses a coke control reactor, a device for preparing low-carbon olefins from an oxygen-containing compound, and a use thereof. The coke control reactor includes a riser reactor and a bed reactor; the bed reactor includes a bed reactor shell, and the bed reactor shell encloses a reaction zone I, a transition zone, and a gas-solid separation zone I from bottom to top; a bed reactor distributor is arranged in the reaction zone I; a coke controlled catalyst delivery pipe is arranged outside the reaction zone I; an upper section of the riser reactor penetrates through a bottom of the bed reactor and is axially inserted in the bed reactor; and an outlet end of the riser reactor is located in the transition zone. The coke control reactor can control the conversion and generation of coke species in a catalyst. On the one hand, inactive large-molecule coke species remaining in a regenerated catalyst are converted into small-molecule coke species; and on the other hand, a riser reactor raw material and a bed reactor raw material can also enter the catalyst to generate highly-active small-molecule coke species to improve the selectivity for ethylene.

摘要： Disclosed are a turbulent fluidized bed reactor, device and method for preparing para-xylene and co-producing light olefins from methanol and/or dimethyl ether and toluene, resolving or improving the competition problem between an MTO reaction and an alkylation reaction during the process of producing para-xylene and co-producing light olefins from methanol and/or dimethyl ether and toluene, and achieving a synergistic effect between the MTO reaction and the alkylation reaction. By controlling the mass transfer and reaction, competition between the MTO reaction and the alkylation reaction is coordinated and optimized to facilitate a synergistic effect of the two reactions, so that the conversion rate of toluene, the yield of para-xylene, and the selectivity of light olefins are increased. The turbulent fluidized bed reactor comprises a first reactor feed distributor and a plurality of second reactor feed distributors; the first reactor feed distributor and the plurality of second reactor feed distributions are sequentially arranged along the gas flow direction in a reaction zone of the turbulent fluidized bed reactor.
