Abstract (en)
[origin: US4875993A] The invention relates to a process and apparatus for catalytic cracking in a fluid phase of a hydrocarbon charge. The process comprises contacting, in ascending or descending flow, the charge and grains of a cracking catalyst in a tubular reactor, ballistically separating the spent catalyst and the cracked charge downstream of the end of said reactor, mixing spent catalyst with grains of at least partially regenerated catalyst having a temperature exceeding that of the grains of spent catalyst, stripping spent catalyst in a dense fluidized phase by means of a fluid injected counter-current into this catalyst regenerating the catalyst under conditions to effect combustion of coke deposited thereon, and recycling regenerated catalyst to feed the reactor.
