Abstract: Molten carbonate fuel cell configurations are provided that allow introduction of an anode input gas flow on a side of the fuel cell that is adjacent to the entry side for the cathode input gas flow while allowing the anode and cathode to operate under co-current flow and/or counter-current flow conditions. Improved flow properties can be achieved within the anode or cathode during co-current flow or counter-current flow operation by diverting the input flow for the anode or cathode into an extended edge seal region (in an extended edge seal chamber) adjacent to the active area of the anode or cathode, and then using a baffle to provide sufficient pressure drop for even flow distribution of the anode input flow across the anode or cathode input flow across the cathode. A second baffle can be used to create a pressure drop at the anode or cathode exit.

Abstract: A method for calibrated multi-mineral, multi-fluid interpretation is provided herein. The method includes generating a multi-mineral, multi-fluid interpretation model for a number of log types using core and/or specialized log data acquired from subsurface region(s) that relate to components within the subsurface region(s). Generating the model includes: (1) for each log type, calibrating component end-members for the log type via an inversion of the core and/or specialized log data relating to the components across all depths of interest; and (2) incorporating the resulting calibrated end-members for the log types into the model. The method also includes generating component volume fraction profiles using log data acquired from analogous subsurface region(s) using the model, wherein the log data relate to any of the log types used to generate the model. Each component volume fraction profile includes a range of component volume fractions that accounts for a degree of uncertainty within the model.

Abstract: Methods are provided for forming supported catalyst compositions and/or corresponding intermediate catalyst products. The catalyst compositions have improved activity for hydroprocessing of distillate boiling range feeds under hydroprocessing conditions where the hydrogen partial pressure in the hydroprocessing environment is reduced or minimized. The catalyst compositions can correspond to supported CoMo catalysts. The improved activity for hydroprocessing under lower pressure conditions is unexpectedly achieved by using a plurality of treatments with organic compounds during the catalyst formation process.

Abstract: Processes and systems for hydrocarbon pyrolysis. In some embodiments, a hydrocarbon can be heated within a convection section of a steam cracking furnace and combined with an aqueous fluid to produce a heated mixture. A heavy feed that includes a plastic material can be introduced into a vessel and a portion of the plastic material can be cracked therein. Liquid and vapor effluents exiting the vessel can be obtained. At least a portion of the liquid effluent can be heated to produce a heated fluid stream that can be recycled to the vessel. The vapor effluent can be combined with the heated mixture to produce a combined mixture that can be heated within the convection section to produce a heated combined mixture. At least a portion of the heated combined mixture can be cracked within a radiant section of the steam cracking furnace to produce a steam cracker effluent.

Abstract: Isomerization of normal paraffins to form branched paraffins may be complicated by significant cracking of C7+ paraffins under isomerization reaction conditions. This issue may complicate upgrading of hydrocarbon feeds having significant quantities of heavier normal paraffins. Cracking selectivity may be decreased by combining one or more naphthenic compounds with a feed mixture comprising at least one C7+ normal paraffin and/or by utilizing tungstated zirconium catalysts having decreased tungsten loading. Further, C5 and C6 normal paraffins may undergo isomerization in the presence of C7+ normal paraffins. Methods for isomerizing normal paraffins may comprise: providing a feed mixture comprising at least C5-C7 normal paraffins and lacking normal paraffins larger than C8; and contacting the feed mixture with a bifunctional mixed metal oxide catalyst under isomerization reaction conditions effective to form a product mixture comprising one or more branched paraffins formed from each of the C5-C7 normal paraffins.
