Abstract: Proppant particulates are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. In complex fracture networks, it can be difficult to deposit proppant particulates fully within the fractures. In addition, low crush strengths may result in problematic fines formation. Polyaromatic hydrocarbons, commonly encountered in various refinery process streams, may serve as an advantageous precursor to proppant particulates. Polyaromatic hydrocarbons may undergo crosslinking under acid-catalyzed conditions in an aqueous solvent in the presence of a surfactant to form substantially spherical particulates that may serve as effective proppant particulates during fracturing operations. In situ formation of the proppant particulates may take place in some cases.

Abstract: Systems and methods are provided for improving the operation of molten carbonate fuel cells that include cathode current collector structures that have reduced contact area with the cathode in order to create increased cathode open surface area. Molten carbonate fuel cells that have cathode collectors with reduced contact area with the cathode can have an increased tendency to suffer structural difficulties during operation, such as formation of gaps between electrolyte and one or both electrodes. Use of a sintered anode in such a fuel cell can reduce or minimize the impact of such structural difficulties. The sintered anode can provide higher pore volume and/or a more stable pore structure and/or increased structural stability in a fuel cell that includes a cathode collector that has a reduced contact area with the cathode. This can maintain a more stable interface between the cathode and electrolyte and/or between the anode and the electrolyte.

Abstract: Capture of hydrogen sulfide from a gas mixture may be accomplished using an aqueous solution comprising an amine. Certain sterically hindered amines may selectively form a reaction product with hydrogen sulfide under kinetically controlled contacting conditions and afford a light phase and a heavy phase above a critical solution temperature, wherein the hydrogen sulfide may be present in either phase. Upon separation of the light phase from the heavy phase, processing of one of the phases may take place to remove hydrogen sulfide therefrom. Recycling of the amine to an absorber tower may then take place to promote capture of additional hydrogen sulfide.

Abstract: A layered cathode structure for a molten carbonate fuel cell is provided, along with methods of forming a layered cathode and operating a fuel cell including a layered cathode. The layered cathode can include at least a first cathode layer and a second cathode layer. The first cathode layer can correspond to a layer that is adjacent to the molten carbonate electrolyte during operation, while the second cathode layer can correspond to a layer that is adjacent to the cathode collector of the fuel cell. The first cathode layer can be formed by sintering a layer that includes a conventional precursor material for forming a cathode, such as nickel particles. The second cathode layer can be formed by sintering a layer that includes a mixture of particles of a conventional precursor material and 1.0 vol % to 30 vol % of particles of a lithium pore-forming compound. The resulting layered cathode structure can have an increased pore size adjacent to the cathode collector to facilitate diffusion of CO2 into the electrolyte interface, while also having a smaller pore size adjacent to the electrolyte to allow for improved electrical contact and/or reduced polarization at the interface between the electrolyte and the cathode.

Abstract: Systems and methods are provided for performing hydrodeoxygenation of bio-derived feeds while maintaining the hydrodeoxygenation catalyst in a sulfided state. During hydrodeoxygenation, a hydrogen-containing stream is provided to the hydrodeoxygenation reactor as a hydrogen treat gas to provide hydrogen for the reaction. In some aspects, the hydrogen treat gas used for hydrodeoxygenation can be formed at least in part from hydrogen that has been used as a stripping gas for removing H2S from a rich amine stream. In other aspects, H2S can be stripped using water vapor, and a resulting overhead HS stream can be compressed prior to incorporation of the H2S into a hydrogen-containing stream. The resulting hydrogen-containing stream can include sufficient H2S to substantially maintain the catalyst in the hydrodeoxygenation stage in a sulfided state.
