Abstract: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.

Abstract: The present disclosure relates to methods and systems for algae cultivation including the integration of electrochemical carbonate production for enhancing algae growth. More particularly, the present disclosure relates to methods and systems for producing a sodium hydroxide from brine using an electrochemical cell, contacting the sodium hydroxide stream with a CO2 gas sweep and producing a carbonate stream, and cultivating an algae slurry in a cultivation vessel comprising at least a portion of the carbonate stream.

Abstract: Bulk metallic catalyst precursors are provided that include a Group VIB metal, such as Ni, a Group VIII metal, such as Mo or W, an organic-compound based component, and an organo-metalloxane polymer or gel. The catalyst precursors can further include a binder. Amorphous sulfided catalysts formed from the catalyst precursors are also provided. The catalyst precursor can have a surface area of about 50 m2/g or less.

Abstract: Systems and methods for algae cultivation and, more particularly, systems and methods for controlling algae cultivation water slurry temperature to optimize algae facility production and facilitation of algae facility commercial deployment in a wide spectrum of environmental locations. Thermal reservoirs comprising temperature-based, phase-transitioning material(s) are integrated with algae cultivation vessels to provide temperature control of cultivating algae slurries.

Abstract: Methods are provided for performing selective hydrodesulfurization on a naphtha boiling range stream naphtha boiling range portion of a feed. It has been unexpectedly discovered that hydrodesulfurization with improved octane retention can be performed by using a catalyst that comprises CoMo supported on a catalyst support that includes a zeotype framework. By using a catalyst support including a zeotype framework, an unexpectedly high amount of octane in the naphtha boiling range portion of the hydrodesulfurized effluent is maintained.
