Abstract:
1. 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 wherein (i) said refractory material comprises a sintered ceramic matrix and durable particles dispersed in said sintered ceramic matrix before the sintering, (ii) said refractory material includes formed pores and a formed porosity of not less than 4 vol %, measured at 20° C., based upon the bulk volume of said refractory material, (iii) at least a part of said formed porosity is derived from said durable particles, and (iv) said durable particles remain heterogeneous or distinct in said ceramic matrix after the sintering; and wherein said formed pores have a D50 diameter not less than the D50 grain size of said refractory material.
