    摘要: 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.

    摘要: Embodiments of the invention relate to processes and apparatus for the washing and recovery of metal-containing catalyst solids in a form suitable for reclamation. More specifically, a catalyst recovery process comprises removing an organic residue with a washing medium from a metal-containing catalyst solids, recovering washed solids, and treating the washed solids under oxidative conditions to form non-reactive solids. The treatment oxidative conditions may be effective to convert the metal(s) into an oxide form and/or may facilitate the removal of remaining organic residue from the washed solids. The treatment of the washed solids may comprise calcination. In some embodiments, the metal-containing catalyst solids may be recovered from a slurry stream, and the process further comprises passing the slurry stream though a separation unit to obtain a catalyst-enriched retentate slurry. In some embodiments, the organic residue comprises a hydrocarbon wax, and the solid catalyst is a hydrocarbon synthesis particulate catalyst.

    摘要: The invention relates to a process and apparatus for controlling afterburning in the regenerator of a FCC unit. The process and apparatus inject steam into the dilute phase within a regenerator to promote combustion of carbon monoxide before it enters the regenerator cyclones, plenum, or flue gas transfer lines.
