Abstract: A reactor and method for the conversion of hydrocarbon gases utilizes a reactor (12, 312, 412, 512, 612, 712) having a unique feed assembly with an original vortex combustion chamber (40, 340, 436, 536, 636, 736), a diverging conduit (48, 348, 448, 548, 648, 748), and a cylindrical reactor chamber (40, 340, 436, 536, 636, 736). This design creates a compact combustion zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (48, 348, 448, 548, 648, 748). The feed streams can be introduced into the reactor at any angle (perpendicular, axial, or something between, or a combination of the above forms) with swirling flow components. This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

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: The present disclosure includes systems, devices, and methods of using a battery cell. The cell may include a container defining a cavity and a plurality of power units, a first conductive member, and/or a second conductive member disposed within the cavity. Each power unit includes a first electrode, a second electrode, and a separator disposed between the first and second electrodes. In some aspects, the first conductive member is coupled to the first electrodes of the plurality of power units and is disposed within the cavity between the first electrodes and at least one of one or more walls of the container to facilitate heat transfer and homogenization of current within the cell.

Abstract: A reactor (12, 128, 198) and method for the conversion of hydrocarbon gases utilizes a reactor (12, 128, 198) having a unique feed assembly (58, 136, 200) with an original vortex disk-like inlet flow spaces (72, 74, 76, 80, 146, 148, 150, 152, 208, 216, 218), a converging-diverging vortex mixing chamber (116), and a cylindrical reactor chamber (40). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit (48) with a constricted neck portion (54). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.
