    摘要: A process for producing light olefins. A feedstock enters a pre-reaction zone and contacts a catalyst comprising at least one silicon-aluminophosphate molecular sieve and produces a gas-phase stream and a catalyst to be regenerated; the gas-phase stream and catalyst to be regenerated enter at least one riser, and the gas-phase stream and catalyst to be regenerated pass from an outlet of the at least one riser and enter a gas-solid rapid separation zone; the separated gas-phase stream enters a separation section; a first portion of the separated catalyst returns to the pre-reaction zone, and a second portion is regenerated in a regenerator; wherein an inlet of the at least one riser extends into the pre-reaction zone, about 60% to about 90% of the height of the at least one riser passes through a heat exchange zone, and the outlet extends into the gas-solid rapid separation zone.

    摘要: The present invention provides a process for increasing ethylene and/or propylene yield during conversion of oxygenates using a system comprising a reactor and a regenerator, wherein the reactor comprises a fluidized bed reactor and a riser reactor, which process increases ethylene and/or propylene yield by using a mixture of the deactivated catalyst from the fluidized bed reactor and the regenerated catalyst from the regenerator in the riser reactor for further cracking the C4+ hydrocarbon stream separated from the product stream.

    摘要: The present invention discloses a process of producing light olefins through the conversion of methanol and ethanol. The process comprises: feeding a first portion of a feed via a distributor at the bottom of a fluidized-bed reactor to a reaction zone containing a catalyst; feeding a second portion of the feed from at least one location above the distributor to the reaction zone; contacting the feed with the catalyst and allowing it to react, to give a stream containing ethylene and propylene; and withdrawing the stream containing ethylene and propylene from the top of the reactor, and passing it to a separation system to separate ethylene and propylene, wherein the first portion of the feed and the second portion of the feed comprises each independently methanol or ethanol or the both, with a proviso that the total feed comprises both methanol and ethanol, and a weight ratio of methanol to ethanol in the total feed is in a range of from 99:1 to 0.1:1.
