Abstract: A method includes containing an algae media within a contactor, introducing a stream of natural gas comprising up to 80 wt % carbon dioxide (CO2) into the contactor, contacting the natural gas on the algae media and thereby allowing the algae media to consume CO2 from the natural gas, and discharging a stream of natural gas comprising 2 wt % or less CO2 from the contactor.

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.

Abstract: A system includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.

Abstract: Scale-up evaluation methods for algal biomass cultivation are provided, and more particularly, simultaneous scale-up evaluation methods for outdoor algal biomass cultivation are provided. The methods control various process variables to isolate the impact of scaling algal biomass cultivation, thereby permitting enhanced scale-up operation design to optimize the quality and quantity of algal biomass.

Abstract: Systems and methods are provided for performing hydrocarbon reforming within a reverse flow reactor environment (or another reactor environment with flows in opposing directions) while improving management of CO2 generated during operation of the reactor. The improved management of CO2 is achieved by making one or more changes to the operation of the reverse flow reactor. The changes can include using an air separation unit to provide an oxygen source with a reduced or minimized content of nitrogen and/or operating the reactor at elevated pressure during the regeneration stage. By operating the regeneration at elevated pressure, a regeneration flue gas can be generated that is enriched in CO2 at elevated pressure. The CO2-enriched stream can include primarily water as a contaminant, which can be removed by cooling while substantially maintaining the pressure of the stream. This can facilitate subsequent recovery and use of the CO2.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer can correspond to a thermally stable metal oxide support layer, such as a metal oxide support layer that is thermally phase stable at temperatures of 800° C. to 1600° C. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle.

Abstract: Systems and methods are provided for hydrogenation of CO2 in a reverse flow reactor environment via a reverse water gas shift reaction. A reverse flow reactor environment is suitable for performing endothermic reactions at high temperatures, where a reactant flow is passed into the reactor in a first portion of the cycle in a first flow direction while a combustion or heating flow is passed into the reactor during a second portion of the reaction cycle from the opposite direction. This can allow for efficient heating of surfaces within the reactor to provide heat for the endothermic reverse water gas shift reaction while reducing or minimizing incorporation of combustion products into the desired reaction products.

Abstract: This invention relates to methods and apparatus for harvesting by-product oxygen from algae ponds or bioreactors (collectively, “algal biofuel production”) for use in an oxygen-requiring process that requires oxygen as a reactant such as syngas, hydrogen, or power production processes, which optionally can be integrated with the algal biofuel production. In some embodiments, the invention provides methods that include a method comprising: collecting oxygen from an algal biofuel production process; and using the collected oxygen in an oxygen-requiring process that requires oxygen as a reactant. In some embodiments, the invention provides systems that include an integrated system comprising: an algal bioreactor that produces biodiesel and oxygen, a pipeline for transporting oxygen to an oxygen-requiring process unit so that the oxygen can be used as reactant in the oxygen-requiring process unit, and the oxygen-requiring process unit.

Abstract: A system for growing algae in a slurry, includes a pond having an inlet and an outlet and a plurality of contiguous elongate channel segments coupled fluidically in sequence between the inlet and the outlet, and the inlet is located at an elevation higher than outlet to allow gravity to flow the slurry from the inlet to the outlet. The system further includes a separation device fluidically coupled to the outlet to receive and separate algae from the slurry.
