Abstract:
1. A fluid catalytic cracking apparatus, comprising: a catalyst regenerator; a riser reactor having a set of main hydrocarbon feed injectors connected thereto and including a conduit portion fluidly connected to said catalyst regenerator for receiving regenerated catalyst, said conduit portion including an angled section located upstream from said set of main hydrocarbon feed injectors, said riser reactor including a vertical portion disposed downstream from said angled section, a plurality of light hydrocarbon feed injectors fluidly connected to a light hydrocarbon feed source; and a plurality of heavy hydrocarbon feed injectors fluidly connected to a heavy hydrocarbon feed source, wherein the plurality of heavy hydrocarbon feed injectors and the main hydrocarbon feed injectors are disposed at approximately the same predetermined elevation on the riser reactor and, together, are slanted in the same direction relative to a flow of catalyst.
