Abstract: A reforming element for a molten carbonate fuel cell stack and corresponding methods are provided that can reduce or minimize temperature differences within the fuel cell stack when operating the fuel cell stack with enhanced CO2 utilization. The reforming element can include at least one surface with a reforming catalyst deposited on the surface. A difference between the minimum and maximum reforming catalyst density and/or activity on a first portion of the at least one surface can be 20% to 75%, with the highest catalyst densities and/or activities being in proximity to the side of the fuel cell stack corresponding to at least one of the anode inlet and the cathode inlet.

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: Systems and methods are provided for improving control of the temperature profile in a cyclic flow reactor, such as a reverse flow reactor, during operation. The improved temperature control is achieved in part based on inclusion of regions having reduced or minimized catalyst density with increased volumetric heat capacity within the reaction zone of the reactor. This improved control over the temperature profile is achieved while reducing or minimizing any loss of reaction capacity due to lowering the amount of catalyst in the reaction zone.

Abstract: Systems and methods are provided for performing reforming in a manner where the flows for providing heat for the endothermic reforming reaction are counter-current to the flows for the reforming reaction. Although the flows are counter-current, the systems and methods also allow the heating profile of the reactor to have a temperature peak toward the middle of the reactor, as opposed to at the end of the reactor. This shift of the temperature peak toward the middle allows for improved heat utilization and recovery during operation of the reactor.

Abstract: A system includes a photobioreactor that provides a channel configured to contain an algae slurry, a duct positioned adjacent the channel and configured to convey a gas, and a barrier separating the duct from the channel and providing one or more apertures to allow a portion of the gas to be injected into the algae slurry from the duct.

Abstract: Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.

Abstract: The present disclosure relates to methods and systems for treating a fluid produced from a biorefinery to remove contaminants, such as metals and sulfur therefrom. Biomass is pyrolysed and activated to form activated carbon used to remove such contaminants. The fluid produced from the biorefinery may be one or more of a biofuel, a biogas, and wastewater.

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: 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.
