A reactor and method for the conversion of hydrocarbon gases utilizes a reactor () having a unique feed assembly with an original vortex combustion chamber (), a diverging conduit (), and a cylindrical reactor chamber (). 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 (). The feed streams can be introduced into the reactor () 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.

Method and reactor for conversion of hydrocarbons

The invention is directed to a chemical reactor () having (a) two or more gas reactor elements () with each gas reactor element () having (i) a first reaction chamber (), and (ii) a feed assembly unit (), (b) a second reaction chamber () coupled with each of the two or more gas reactor elements () and configured to independently receive two or more product streams from the two or more gas reactor elements (); and optionally, (c) a gas converging section () located downstream to the second reaction chamber (). The invention is further directed to a method of producing chemical products using the chemical reactor () of the present invention.

Reactor system for the production of high value chemical products

A fluid-solids contactor comprising an annular rotating fluidized bed and a method of using the same are disclosed. The fluid-solids contactor includes a vessel and a plurality feed inlets disposed thereon. The vessel comprises a stationary inner wall, an outer wall, and a chamber formed between the stationary inner wall and the outer wall. The feed inlets are configured to create an annular rotating bed with mixture of solids and a fluid when the solid particles and a fluid are fed into the chamber. The stationary inner wall of the vessel is permeable to the fluid such that the fluid from the chamber can be continuously withdrawn from the solids to the space within the stationary inner wall of the vessel.

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.

Reactor for pyrolysis conversion of hydrocarbon gases

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.
