Abstract: The present invention features a system and method for circulating catalyst between a reactor system and a regenerator system. A circulating catalyst system includes a reactor system, a regenerator system, and a distribution unit. The reactor system and regenerator system are adapted to exchange catalyst. The regeneration system preferably includes a regeneration zone adapted for the contact of catalyst with a regeneration gas. The system and method are adapted so that more than one regeneration gas may contact catalyst. The distribution unit is adapted to control the percentage of catalyst contacting each regeneration gas. Thus, the distribution unit is adapted to select the percentages so as to maintain the reactor system and regeneration system under a heat balance regime. Heat is preferably transferred from the regenerator system to the reactor system by an exchange of catalyst.

Abstract: A process for reducing C2-C9 olefin formation by recycling them to a Fischer-Tropsch hydrocarbon synthesis process and promoting recycled olefins chain growth comprises contacting a gas feed comprising a mixture of H2 and CO with a catalyst in a reactor system at conditions effective to produce a hydrocarbon product stream including C2-C9 olefins, separating a C2-C9 olefins-rich stream from the hydrocarbon product stream to form a light olefin recycle stream and recycling the light olefin recycle stream to the reactor system at a point in the reactor system where the H2:CO ratio is low relative to the H2:CO ratio in the rest of the reactor system. Depending on whether the initial H2:CO ratio is greater or less than the usage ratio of the selected catalyst, the recycled olefins can be returned to the system up- or downstream of the reactor system.

Abstract: A process is disclosed for regenerating a catalyst used in a process for synthesizing hydrocarbons. The synthesis process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons. The regeneration process involves contacting a deactivated Fischer-Tropsch catalyst with a regeneration gas under regeneration-promoting conditions that include a pressure lower than the mean Fischer-Tropsch reaction pressure, for a period of time sufficient to reactivate the Fischer-Tropsch catalyst.
