Abstract: This application relates to renewable diesel production and to production of renewable naphtha in a renewable diesel unit. Disclosed herein is an example of a method of renewable diesel production. Examples embodiments of the method may include hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock; contacting at least a portion of the hydrotreated biofeedstock with a dewaxing catalyst to produce a renewable diesel product and a renewable naphtha product; separating the renewable diesel product and the renewable naphtha product in a product splitter; and monitoring an octane number of the renewable naphtha product with an analyzer.

Abstract: Systems and methods are provided for conversion of oxygenate feeds to lubricant and/or distillate boiling range compounds with desirable properties by first selectively converting oxygenates to light olefins and then converting the light olefins to distillate and lubricant boiling range compounds with beneficial properties. The distillate boiling range products can have an unexpectedly high cetane, while the lubricant boiling range products can have an unexpectedly high viscosity index. The ability to form the distillate boiling range products and lubricant boiling range products is facilitated by using a Ni-enhanced oligomerization catalyst.

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: 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 MOF catalysts, which may be prepared from a precursor metal-organic framework (MOF). A MOF catalyst may be prepared by exchanging one or more organic linking ligands of the precursor MOF for an organic linking ligand having a different acidity and/or electron-withdrawing properties, which, in turn, may affect catalytic activity.

Abstract: Systems and methods are provided for conversion of a combined feed of oxygenates (such as methanol or dimethyl ether) and olefins to a high octane naphtha boiling range product with a reduced or minimized aromatics content. The oxygenate conversion can be performed under conditions that reduce or minimize hydrogen transfer. Optionally, a catalyst that further facilitates formation of branched paraffins can be used, such as a catalyst that has some type of 12-member ring site available on the catalyst surface.

Abstract: Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM-48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.

Abstract: Processes for the catalytic conversion of alcohols and/or ethers to olefins over zeolite catalysts are described. Self-bound ZSM-5 and metal containing variants, such as Zn ZSM-5, produce high yields of olefins, particularly C3+ olefins, between 250 and 450° C.

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.

Abstract: Methods are provided for formulation of catalysts with improved catalyst exposure lifetimes under oxygenate conversion conditions. In various additional aspects, methods are described for performing oxygenate conversion reactions using such catalysts with improved catalyst exposure lifetimes. The catalyst formulation methods can include formulation of oxygenate conversion catalysts with binders that are selected from binders having a surface area of roughly 250 m2/g or less, or 200 m2/g or less. In various aspects, during formulation, a weak base can be added to the zeotype crystals, to the binder material, or to the mixture of the zeotype and the binder. It has been unexpectedly discovered that addition of a weak base, so that the weak base is present in at least one component of the binder mixture prior to formulation, can result in longer catalyst exposure lifetimes under methanol conversion conditions.
