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 device for mixing two gas streams, the device includes: an inner pipe, wherein: the inner pipe is arranged substantially concentrically within an outer pipe and forms an annulus between an outer diameter of the inner pipe and an inner diameter of the outside pipe; the inner pipe is closed at a downstream end; and the inner pipe comprises a plurality of perforations; and the outer pipe, wherein: a downstream end of the outer pipe extends into a reactor; the outer pipe is closed at the downstream end; and the downstream end of the outer pipe comprises a plurality of perforations. The mixed gas stream can enter the reactor. The reactor can be an Oxidative Coupling of Methane (OCM) reactor.
