Abstract: Vessel and support beam assembly includes a vessel having a cylindrical wall defining an interior chamber having a generally circular shape of diameter D in plan view, and a support assembly disposed within the interior chamber. The support assembly includes an inner hub defining an open central region, and a plurality of spokes extending radially from the inner hub. Each spoke is aligned radially with the cylindrical wall of the vessel and joined thereto. At least one open outer region is defined between circumferentially adjacent spokes.

Abstract: The present invention is an improved design and operation of a short contact time Fluid Catalytic Cracking (FCC) Reactor wherein the upper internal riser and a lower internal riser are in fluid connection with one another and provide an improved disengaging zone for entraining the vapors from the dilute phase area of the FCC reactor. Detailed preferred embodiments include improvements over the prior art to the internal central riser, riser termination apparatus, cyclone separators, and a coke mitigation baffle system, as well as associated improved fluid catalytic cracking processes utilizing the novel reactor design.
