This patent describes improvement in a facility for converting alkanes into gasoline, the facility including a fluid catalytic cracking system and an olefin oligomerization reactor. The improvement comprises: a first valved conduit means for withdrawing a controlled stream of the regenerated catalyst from the first regenerator means; a dehydrogenation reactor in valved communication with the first regenerator means, through the first valved conduit means the dehydrogenation reactor having a dehydrogenation zone at a temperature below those prevailing in the first regeneration zone, the dehydrogenation reactor being located externally relative to the fluid catalytic cracker reactor and first regenerator; means for introducing a lower alkane feedstream into the dehydrogenation zone in an amount sufficient to maintain hot withdrawn catalyst in a state of fluidization in the dehydrogenation reactor while the catalyst is being cooled therein; a second valved conduit means for transporting cooled catalyst from the dehydrogenation zone to the first regeneration zone.
