Abstract	In one aspect, the invention includes a reactor apparatus for pyrolyzing a hydrocarbon feedstock, said apparatus including: a reactor component comprising a refractory material in oxide form, the refractory material having a melting point of no less than 2060° C. and which remains in oxide form when exposed to a gas having carbon partial pressure of 10−22 bar and oxygen partial pressure of 10−10 bar, at a temperature of 1200° C.; wherein said refractory material has no less than 4 vol % formed porosity, measured at 20° C., based upon the bulk volume of said refractory material. In another embodiment, the refractory material has total porosity in the range of from 4 to 60 vol %.
