An integrated process is disclosed for (i) catalytically cracking (FCC) a heavy hydrocarbon feedstock, (ii) obtaining a combined propane/propylene stream, and (iii) reacting the propylene of the combined propane/propylene stream with benzene to produce a cumene product stream. The integrated process comprises contacting a heavy hydrocarbon feedstock with a hydrocarbon cracking catalyst in a fluidized reactor zone to produce a hydrocarbon effluent stream that includes propane and propylene. The process then further comprises separating the combined propane/propylene stream from the hydrocarbon effluent stream, passing the combined propane/propylene stream to an alkylation reactor, and reacting at least some of the propylene of the combined propane/propylene stream with benzene in the alkylation reactor to produce cumene.
