    Abstract: Methods and systems for the conversion of hydrocarbon feedstocks, in particular, naphtha feedstocks, into a hydrocarbon product stream containing a high yield of high-octane gasoline and chemicals products. In particular, the conversion takes place over a series of functionally distinctive catalyst beds, at least one of which includes a modified zeolitic catalyst comprising a zeolite, a transition metal, and optionally a binder. Systems provided include a hydrocarbon feed stream, which may be full-range naphtha, a hydrocarbon product stream, and a plurality of functionally distinctive catalyst beds arranged in series, wherein at least one of the catalyst beds comprises a modified zeolitic catalyst. A hydrocarbon feed stream may be conveyed through the plurality of functionally distinctive catalyst beds, producing an intermediate hydrocarbon stream between each, under conditions effective to convert the hydrocarbon feed stream to a hydrocarbon product stream comprising high-octane gasoline, xylenes, benzene, and/or toluene.

    Abstract: A system for growing algae includes a gas concentrator configured to receive a first gas containing CO2 at a first concentration and discharge a second gas containing CO2 at a second concentration higher than the first concentration, and a photobioreactor containing algae in an algae slurry and fluidically coupled to the gas concentrator to receive the second gas. A recycling line extends from a gas outlet on the photobioreactor to remove a third gas from the photobioreactor for future use in the photobioreactor.

    Abstract: Systems and methods are provided for improving thermal management and/or efficiency of reaction systems including a reverse flow reactor for performance of at least one endothermic reaction and at least one supplemental exothermic reaction. The supplemental exothermic reaction can be performed in the recuperation zone of the reverse flow reactor system. By integrating the supplemental exothermic reaction into the recuperation zone, the heat generated from the supplemental exothermic reaction can be absorbed by heat transfer surfaces in the recuperation zone. The adsorbed heat can then be used to heat at least one of the fuel and the oxidant for the combustion reaction performed during regeneration, thus reducing the amount of combustion that is needed to achieve a desired temperature profile at the end of the regeneration step.
