    Abstract: Systems and methods for regenerating a spent catalyst are provided. The method can include mixing a spent catalyst with a carrier fluid to provide a mixture. The spent catalyst can include carbon deposited on at least a portion thereof. The carrier fluid can include an oxygen containing gas. The mixture can be introduced to or above an upper surface of a dense phase catalyst zone disposed within a regenerator. A gas can be introduced to a lower zone of the dense phase catalyst zone. At least a portion of the carbon deposited on the catalyst can be combusted to provide a flue gas, heat, and a regenerated catalyst.

    Abstract: This invention provides processes for transporting catalyst, preferably in an oxygenate to olefins reaction system. In one embodiment, an oxygenate contacts molecular sieve catalyst particles in a reactor under conditions effective to form an effluent stream comprising light olefins and forming coked catalyst particles. At least a portion of the coked catalyst particles are transported from the reactor or a device associated therewith to a catalyst regenerator through a conduit in a fluidized manner with a fluidizing medium comprising air and steam. At least a portion of the coked catalyst particles are regenerated in the catalyst regenerator to form regenerated catalyst particles, which are ultimately directed back to the reactor.

    Abstract: A process for the production of phenyl alkanes by catalytic alkylation on a solid acid catalyst employs at least one moving-bed reactor. This process comprises a catalytic alkylation stage of an aromatic compound by at least one olefin that has 9 to 16 carbon atoms per molecule, combined with a catalyst reactivation circuit. Each reactor contains n reaction zones, whereby each of said zones consists of an acidic solid catalyst, optionally different from one zone to the next. Entering each reaction zone, a fraction of the total amount of olefins necessary to the alkylation reaction is introduced. The phenyl alkanes that are obtained by the process according to the invention are particularly suitable for the production of detergents.
