Abstract: A pyrolysis reactor (12) and method for the pyrolysis of hydrocarbon gases (e.g., methane) utilizes a pyrolysis reactor (12) having a unique burner assembly (44) and pyrolysis feed assembly (56) that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a burner conduit (46) with a constricted neck portion or nozzle (52). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the burner conduit (46). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the burner conduit (46) and a portion of combustion products circulates in the burner assembly (44). This provides conditions suitable for pyrolysis of hydrocarbons or light alkane gas, such as methane or natural gas.

Abstract: A method of making light olefins is described. The method involves producing an alkyne in a pyrolysis process. The alkyne is catalytically hydrogenated in a hydrogenation zone to produce a product stream containing a light olefin. A byproduct stream from the pyrolysis process comprises carbon oxide and hydrogen. The byproduct stream is treated to convert the carbon oxide and the hydrogen to an oxygenated product in a carbon oxide conversion zone, which can then be converted to an olefin in an oxygenate to olefin process.

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 tot he 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.

Abstract: The inventing relates to hydrocarbon conversion, and more particularly to catalytically converting alkane in the presence of oxygen released from an oxygen storage material. Conversion products include C2 hydrocarbon, such as C2+ olefin. The hydrocarbon conversion process can be an oxidative coupling reaction, which refers to the catalytic conversion of methane in the presence of oxidant to produce the olefin product. Flow-through reactors can be used to carry out oxygen storage and the oxidative coupling reaction. Reverse-flow reactors are examples of flow-through reactors, which can be used to carry out oxygen storage and the oxidative coupling reaction.
