Abstract: Systems and methods for algae processing and, more particularly, to systems and methods for having integrated solar steam systems. Trapped heated air accumulated within the solar steam system, such as a greenhouse-enclosed solar steam system, is swept over a cultivated algae slurry in order to facilitate drying thereof and increasing the thermal efficiency of a biofuel algae facility.

Abstract: This disclosure relates to a method for improving air release and water separation in a lubricating oil. The method involves formulating a composition comprising at least one lubricating oil base stock as a major component, and one or more lubricating oil additives, as a minor component. The one or more lubricating oil additives include a mixture of antifoam agents. The mixture of antifoam agents includes at least one polysiloxane and at least one acrylate polymer. During operation of a lubricating system containing the lubricating oil, release of entrained air in the lubricating oil is improved, as determined by ASTM D-3427-15, and water separation from the lubricating oil is improved, as determined by ASTM D-1401-18b, as compared to release of entrained air and water separation achieved using a lubricating oil containing other than the mixture of antifoam agents. This disclosure also relates to lubricating oils having a mixture of antifoam agents including at least one polysiloxane and at least one acrylate polymer.

Abstract: The application relates to processes and systems that use a furfural compound for producing five-membered carbocyclic rings that are unsaturated, such as cyclopentene and cyclopentadiene. Examples methods for conversion of furfural compounds may include converting a furfural compound to at least a five-membered, saturated carbocyclic ring, and converting the five-membered, saturated carbocyclic ring in a presence of a catalyst to at least a five-membered, unsaturated carbocyclic ring.

Abstract: Systems and methods for cultivating and harvesting algal biomass using cultivation vessels having integrated therewith one or more harvesting systems. Algae cells are cultivated in a cultivation system and concentrated algal biomass is collected using the integrated one or more harvesting systems. The integrated cultivating and harvesting systems reduce costs, energy, and time compared to traditional harvesting methods.

Abstract: 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: Marine fuel compositions that are low sulfur and have improved wax flow viscosity are disclosed. An example marine fuel composition may have the following enumerated properties: a sulfur content of about 0.50% or less by weight of the marine fuel composition; a density at 15° C. of about 0.86 g/cm3 to about 1.01 g/cm3; a kinematic viscosity at 50° C. of about 1 centistoke to about 700 centistokes; and a ratio of kinematic viscosity to wax flow viscosity of greater than 1, wherein the wax flow viscosity is determined using a minimum operating viscosity of about 8 centistokes at 50° C.

Abstract: A system for growing algae includes a gas concentrator configured to receive a first gas containing CO2 at a first concentration and discharge a second gas containing CO2 at a second concentration higher than the first concentration, and a photobioreactor containing algae in an algae slurry and fluidically coupled to the gas concentrator to receive the second gas. A recycling line extends from a gas outlet on the photobioreactor to remove a third gas from the photobioreactor for future use in the photobioreactor.

Abstract: A method includes containing an algae media within a contactor, introducing a stream of natural gas comprising up to 80 wt % carbon dioxide (CO2) into the contactor, contacting the natural gas on the algae media and thereby allowing the algae media to consume CO2 from the natural gas, and discharging a stream of natural gas comprising 2 wt % or less CO2 from the contactor.

Abstract: Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.
