    摘要: A process for producing at least one light olefin comprising: (a) contacting a first raw material comprising methanol with a least one catalyst in a first reaction zone to produce at least one light olefin and at least one inactivated catalyst; (b) transporting the at least one inactivated catalyst to a first regeneration zone to produce at least one first regenerated catalyst, and transporting a portion of the at least one first regenerated catalyst to the first reaction zone; (c) transporting another portion of the at least one first regenerated catalyst to a second regeneration zone to obtain at least one second regenerated catalyst; and (d) transporting the at least one second regenerated catalyst to a second reaction zone, and contacting the at least one second regenerated catalyst with a second raw material comprising C4 olefins to produce a product stream II comprising at least one light olefin.

    摘要: A process for producing at least one light olefin comprising: (a) contacting a first raw material comprising methanol with a least one catalyst comprising at least one silicon-aluminophosphate molecular sieve in a first reaction zone to produce a product stream I comprising at least one light olefin and at least one inactivated catalyst; (b) transporting the at least one inactivated catalyst to a first regeneration zone to produce at least one first regenerated catalyst, and transporting a portion of the at least one first regenerated catalyst to the first reaction zone, wherein the at least one first regenerated catalyst comprises a carbon deposit present in an amount ranging from about 0.8% to about 2.5% by weight relative to the total weight of the at least one first regenerated catalyst; (c) transporting another portion of the at least one first regenerated catalyst to a second regeneration zone to obtain at least one second regenerated catalyst, wherein the at least one second regenerated catalyst comprises a carbon deposit present in amount of less than about 0.2% by weight relative to the total weight of the at least one second regenerated catalyst; and (d) transporting the at least one second regenerated catalyst to a second reaction zone, and contacting the at least one second regenerated catalyst with a second raw material comprising C4 olefins to produce a product stream II comprising at least one light olefin.
