Abstract: Systems and methods are provided for oligomerization of olefins to distillate boiling range products while also recycling naphtha boiling range olefins as part of the feed. By performing the olefin oligomerization while also recycling naphtha boiling range olefins, it has been discovered that the resulting distillate boiling range products can have an unexpected improvement in diesel combustion quality, such as an unexpected improvement in cetane rating. In order to manage coke formation and maintain consistent activity profile for the oligomerization catalyst, the reaction can be performed in a moving bed reactor. Additional temperature control can be maintained by the recycling of the naphtha boiling range portions of the oligomerization product back to the reactor.

Abstract: Zeolitic and molecular organic framework materials as catalysts suitable for generating branched olefins from linear olefins, thereby increasing the octane of a composition comprising the linear olefins. In particular, catalyst may exhibit selectivity for methyl-shift isomerization over cracking, alkylation, and oligomerization.

Abstract: Systems and methods are provided for conversion of oxygenate-containing feeds to a hydrocarbon effluent that includes a naphtha boiling range portion with an increased research octane number and/or increased octane rating. The conditions for converting the oxygenate-containing feed can correspond to conversion conditions for fluidized bed operation and/or moving bed operation, with a low acidity catalyst that also includes phosphorus to improve the hydrogen transfer rate relative to the expected hydrogen transfer rate for a low acidity catalyst. In addition to providing a naphtha fraction with an improved research octane number and/or octane rating, the amount of durene in the naphtha fraction can be reduced or minimized.

Abstract: A fuel cell is provided including an anode configured to receive, and allow to pass through, an anode process gas, a cathode configured to receive, and allow to pass through, a cathode process gas, and an electrolyte matrix layer separating the anode and the cathode. One of the anode or the cathode has an extended edge seal chamber, and the fuel cell is configured to receive the anode process gas and the cathode process gas in substantially perpendicular directions relative to each other, and the extended edge seal chamber is configured to allow the anode process gas and the cathode process gas to pass through the anode and the cathode in substantially parallel flow paths.

Abstract: This application relates to methods and systems for the conversion of hydrocarbon feedstocks, in particular, naphtha feedstocks, into a hydrocarbon product stream containing a high yield of high-octane gasoline and chemicals products. In particular, the conversion takes place over a series of functionally distinctive catalyst beds, at least one of which includes a modified zeolitic catalyst comprising a zeolite, a transition metal, and optionally a binder. Systems provided include a hydrocarbon feed stream, which may be full-range naphtha, a hydrocarbon product stream, and a plurality of functionally distinctive catalyst beds arranged in series, wherein at least one of the catalyst beds comprises a modified zeolitic catalyst. A hydrocarbon feed stream may be conveyed through the plurality of functionally distinctive catalyst beds, producing an intermediate hydrocarbon stream between each, under conditions effective to convert the hydrocarbon feed stream to a hydrocarbon product stream comprising high-octane gasoline, xylenes, benzene, and/or toluene

Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more large pore zeolitic catalysts, which may be prepared from a precursor zeolite. In some examples, a large pore zeolitic catalyst may be utilized to selectively reduce the endpoint of a hydrocarbon composition.

Abstract: Molten carbonate fuel cell configurations are provided that allow for 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. It has been discovered that 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 as the anode output flow or cathode output flow exits from the active area into a second extended edge seal region (in a second extended edge seal chamber) prior to leaving the fuel cell.

Abstract: Systems and methods are provided for integration of electrolysis with biomass gasification to generate synthesis gas that can be used for production of renewable fuels and/or other hydrocarbonaceous compounds. The hydrocarbonaceous compounds can include compounds formed by chemical synthesis, such as alkanes formed by a Fischer-Tropsch process or methanol formed by a methanol synthesis process; or the hydrocarbonaceous compounds can include compounds formed by fermentation, such as alcohols formed by micro-organisms that use the synthesis gas as an input feed.
