Abstract
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.
