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