Appl. No.:

17/288179

- Bergen op Zoom, NL
Byeongjin Baek - Katy TX, US

International Classification:

B01J 19/24
C07C 5/48
C10G 9/36

Abstract:

A reactor () and method for the conversion of hydrocarbon gases utilizes a reactor () having a unique feed assembly () with an original vortex disk-like inlet flow spaces (), a converging-diverging vortex mixing chamber (), and a cylindrical reactor chamber (). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit () with a constricted neck portion (). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

Abstract:

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