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: Systems and methods are provided for conversion of light paraffinic gases to form liquid products in a process performed in a fixed bed radial-flow reactor. The light paraffins can correspond to C3+ paraffins. Examples of liquid products that can be formed include C6-C12 aromatics, such as benzene, toluene, and xylene. The fixed bed radial-flow reactor can allow for improved control over the reaction conditions for paraffin conversion in spite of the fixed bed nature of the reactor. This can allow the process to operate with improved efficiency while reducing or minimizing the complexity of operation relative to non-fixed bed reactor systems.

Abstract: A reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.
