Abstract
Apparatuses and associated methods for forming olefins from saturated hydrocarbon feedstock are disclosed herein. In one embodiment, a carrier gas is introduced at a supersonic velocity to a feedstock injector section. A feedstock gas is introduced to the carrier gas stream using feedstock injectors that are offset in the streamwise direction one from another. The upstream feedstock injectors are positioned to inject feedstock gas to create plumes that improve penetration depth of the feedstock gas and reduce pressure losses at the downstream feedstock injectors. The feedstock gas can be regeneratively preheated by cooling the convergent-divergent nozzle. Water, steam and/or hydrogen gas can be injected into the apparatus for cooling the throat of the convergent-divergent nozzle.
