Abstract:
An integrated process for producing C3-C4 olefins or di-olefins including: contacting a hydrocarbon feed and a catalyst feed in a fluidized dehydrogenation reactor under conditions such that a product mixture is formed and the catalyst is at least partially deactivated; transferring the product mixture and the catalyst from the reactor to a cyclonic separation system under conditions such that the product mixture is converted to form a new product mixture and is separated from the catalyst; transferring at least a portion of the catalyst to a regenerator vessel and heating it in order to combust the coke deposited thereon; subjecting the catalyst to a conditioning step to form an oxygen-containing, at least partially reactivated catalyst; and transferring the partially reactivated catalyst back to the fluidized dehydrogenation reactor.

Claim (Index 1):
An integrated process for producing C3-C4 olefins or C3-C4 di-olefins comprising the steps of:\n ( 1 ) (a) contacting, in a fluidized dehydrogenation reactor,\n (i) a C3-C4 hydrocarbon feed and \n (ii) a catalyst feed comprising a catalyst; \n under conditions such that a step (1)(a) product mixture, comprising a C3-C4 target olefin or di-olefin, hydrogen and unreacted C3-C4 hydrocarbon feed, is formed; \n and\n the catalyst has coke deposited thereon and is at least partially deactivated such that it forms an at least partially deactivated catalyst; and \n (b) transferring the step (1)(a) product mixture and the at least partially deactivated catalyst from the fluidized dehydrogenation reactor to a cyclonic separation system, and under conditions such that the step (1)(a) product mixture is converted to form a step (1)(b) product mixture; and thereafter substantially separating the step (1)(b) product mixture and the at least partially deactivated catalyst from each other; (c) transferring at least a portion of the at least partially deactivated catalyst to a regenerator vessel and heating the at least partially deactivated catalyst therein to a combustion temperature of from about 660\u00b0 C. to about 850\u00b0 C. in order to combust the coke deposited on the at least partially deactivated catalyst therein, the heating forming a heated, further deactivated catalyst which has an activity for dehydrogenating the C3-C4 hydrocarbon feed that is less than that of the at least partially deactivated catalyst, and, (d) subjecting the heated, further deactivated catalyst to a conditioning step, comprising maintaining the heated, further deactivated catalyst at a temperature of at least 660\u00b0 C. under a flow of an oxygen-containing gas for more than 2 minutes, to form an oxygen-containing, at least partially reactivated catalyst that has an activity for dehydrogenating the C3-C4 hydrocarbon feed that is greater than that of the at least partially deactivated catalyst; and (e) transferring the at least partially reactivated catalyst back to the fluidized dehydrogenation reactor.
