Abstract:
1. A fluid coking reactor which comprises a dense bed reaction section of circular horizontal cross-section about a vertical axis and confined by a reactor wall in which bed a heavy oil feed is thermally cracked to form solid coke and vaporous cracking products, the reactor having: a base region at which fluidizing gas is injected to fluidize a bed of finely-divided solid coke particles in the dense bed reaction section, a plurality of heavy oil inlet rings located around the periphery of the reactor wall in the reaction section and at multiple elevations above the base region, a top region at which gas and finely divided particulate coke solids exit the reaction section, a plurality of the frusto-conical baffles located at multiple elevations in the dense bed reactor section above the base region of the reactor, each baffle being located between a successive pair of the heavy oil inlets rings and depending from an upper edge at the reactor wall to extend downwards and radially inwards from the reactor wall to a lower, inner edge defining a central aperture.
