Abstract: Systems and methods for upgrading natural gas that may include the division of a natural gas feed steam into two parts—one that is partially oxidized into syngas and a second that is “dry” reformed into syngas with the assistance of heat from the partial oxidation. Each of the resulting syngas products may then be combined, and after water is condensed from the syngas, the combined syngas product may be converted to dimethyl ether.

Abstract: A moving bed reactor is provided that can allow facilitate performing a reaction involving a three-phase flow under co-axial flow conditions for the solid and liquid portions of the three phase flow, while the gas portion of the three-phase flow is exposed to the solids under radial flow conditions. Methods for using such a moving bed reactor to perform a reaction, such as upgrading of a feed to distillate products, are also provided.

Abstract: Systems and methods are provided for controlling the flow and transport of catalyst particles within a reaction system. The flow of catalyst particles can be managed using a rotating disc or wheel that is configured within a roller volume to allow for control over the rate of catalyst flow while reducing or minimizing attrition of the catalyst particles. This can be achieved in part by maintaining a relationship between the center of the rotating disc, the inlet for catalyst particles to the roller volume, and the top wall of the roller volume so that catalyst particles are not exposed to compressive forces and/or abrasion during rotation of the disc. Additionally or alternately, the disc and roller volume surfaces can be configured to reduce or minimize the potential for catalyst particles to become trapped in “dead space” regions within the roller volume. By using a disc to provide force for transport of particles through the roller volume, the speed of catalyst movement can be controlled at relatively slow catalyst flow rates with a reduced or minimized risk for clogging or plugging within the roller volume.

Abstract: A method for reducing CO2 emissions from steam cracking operations can include: introducing an oxygen-rich stream comprising oxygen and from 0 wt % to 15 wt % nitrogen to a vessel; introducing hydrocarbon combustion fuel to the vessel; combusting oxygen and hydrocarbon combustion fuel in the vessel to (1) produce a flue gas comprising carbon dioxide and water and (2) heat a cracking coil passing through the vessel; and performing a steam cracking reaction in the cracking coil passing through the vessel.
