ABSTRACT:
In one aspect, the invention includes an apparatus for pyrolyzing a hydrocarbon feedstock in a regenerative pyrolysis reactor system, the apparatus comprising a regenerative pyrolysis reactor comprising a stabilized refractory grade zirconia in a reactive region of the reactor system. In another aspect, this invention includes a method for pyrolyzing a hydrocarbon feedstock using a reverse flow regenerative pyrolysis reactor comprising the steps of providing a reverse flow regenerative pyrolysis reactor including a stabilized refractory grade zirconia in a heated reaction zone of the reactor; and pyrolyzing a hydrocarbon feedstock within the reactive region.
