Abstract: Systems and methods are provided for improving thermal management and/or efficiency of reaction systems including a reverse flow reactor for performance of at least one endothermic reaction and at least one supplemental exothermic reaction. The supplemental exothermic reaction can be performed in the recuperation zone of the reverse flow reactor system. By integrating the supplemental exothermic reaction into the recuperation zone, the heat generated from the supplemental exothermic reaction can be absorbed by heat transfer surfaces in the recuperation zone. The adsorbed heat can then be used to heat at least one of the fuel and the oxidant for the combustion reaction performed during regeneration, thus reducing the amount of combustion that is needed to achieve a desired temperature profile at the end of the regeneration step.

Abstract: A method suitable for use in investigating synthesis conditions for metal-organic frameworks may include: identifying synthesis conditions that includes a first solvent system by which a metal-organic framework is successfully synthesized; and synthesizing the metal-organic framework under substantially the same synthesis conditions but with a second solvent system (or a comparable solvent system) having a difference (Ra) between Hansen solubility parameters of 5 MPa0.5 or less as compared to the first solvent system.

Abstract: A system includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.

Abstract: A method of producing a acid/metal bifunctional catalyst may include: mixing an acid catalyst, a metal catalyst, and a fluid to produce a slurry, wherein the acid catalyst is present at 50 wt % or less relative to a total catalyst weight in the slurry; heating the slurry; producing a powder from the slurry; and calcining the powder to produce the acid/metal bifunctional catalyst. Such acid/metal bifunctional catalyst would be useful in the direct conversion of syngas to dimethyl ether as well as other reactions.

Abstract: Systems and methods are provided for performing selective catalytic reduction on engine exhaust using ethanol from the engine fuel as the reducing agent. Fuel from a fuel tank or other fuel source can be passed through a separation module to produce a fuel stream with a reduced ethanol content and an ethanol-enriched fraction. After combustion of fuel under lean conditions, the combustion exhaust can be exposed to a catalyst system in the presence of the ethanol-enriched fraction.

Abstract: Systems and methods are provided for separating a feedstock into a plurality of separation products using dividing wall column technology that includes a plurality of dividing walls. Including a plurality of dividing walls in the column can provide reduced energy consumption and reduced equipment footprint for production of a plurality of high purity distillation products. The systems and methods can allow for separation of a large number of products from a feed while having a reduced or minimized number of liquid splits and/or vapor splits.

Abstract: Systems and methods are provided for modifying or selecting processing conditions for bright stock formation based on compositional characterization of the feedstock and/or bright stock products. In some aspects, the compositional information can include Z-class characterization of the components of a feed and/or bright stock product, optionally in combination with carbon number and/or molecular weight for the components. The compositional information can be used to select processing conditions to allow for removal and/or modification of selected components within a bright stock in order to improve throughput and/or provide desirable cold flow properties.

Abstract: Compositions corresponding to marine diesel fuels, fuel oils, jet fuels, and/or blending components thereof are provided that include at least a portion of a natural gas condensate fraction. Natural gas condensate fractions derived from a natural gas condensate with sufficiently low API gravity can provide a source of low sulfur, low pour point blend stock for formation of marine diesel and/or fuel oil fractions. Natural gas condensate fractions can provide these advantages and/or other advantages without requiring prior hydroprocessing and/or cracking.
