In one aspect, the invention includes a refractory material for a pyrolysis reactor for pyrolyzing a hydrocarbon feedstock, the refractory material comprising an yttria stabilized zirconia, the refractory material comprising at least 21 wt.% yttria based upon the total weight of the refractory material. In another aspect, this invention includes a method for mitigating carbide corrosion while pyrolyzing a hydrocarbon feedstock at high temperature using a pyrolysis reactor system comprising the steps of: (a) providing a pyrolysis reactor system comprising stabilized zirconia in a heated region of the reactor, the stabilized zirconia including at least 21 wt.% yttria and having porosity of from 5 vol.% to 28 vol.%; (b) heating the heated region to a temperature of at least 1500°C; and (c) pyrolyzing a hydrocarbon feedstock within the heated region. |
