Abstract: A method and system for direct quantification of the concentration of biomolecules in algal biomass. The biomolecules include lipids, proteins, and carbohydrates. An algae slurry is cultivated within a cultivation vessel, and algal biomass is harvested therefrom. A portion of biomass is analyzed using solvent-lipid analysis to extract lipids and nuclear magnetic resonance spectroscopy is used to quantify the biomolecular concentration of the biomass.

Abstract: Embodiments of an invention disclosed herein relate to methods for performing formation evaluation of a formation or formation's surrounding to identify and characterize the abundance and morphology of non-ionic conductor grains, “c-grains”, within the formations that are evaluated by formation evaluation (FE) tools. The methods and related systems as disclosed herein are directed to correcting any existing FE logs that can be adversely affected by the presence of c-grains in the detection volume of FE tools, and/or obtaining new FE information that is unavailable by the application of existing FE methods.

Abstract: Isobutanol may be converted into predominantly C12+ olefin oligomers under specified conditions. Such methods may comprise: contacting a feed comprising isobutanol with a zeolite solid acid catalyst having a MWW framework under conditions effective to convert the isobutanol into a product comprising Can olefin oligomers, wherein n is an integer having a value of two or greater and about 80 wt. % or greater of the Can olefin oligomers are larger than C8.

Abstract: Systems and methods are provided for interfacing multiple layers of optimization for a model of one or more processes in a processing environment to achieve increased or maximized stability in the underlying layer. To improve consistency between the solutions at the different model levels, the lower level of optimization can have extra constraints added to the optimization problem which target variables at their unconstrained values in the upper layer of optimization. The systems and methods can facilitate selection of variables to receive an external target such that stability of the solution is improved or maximized. This can be achieved, at least in part, by identifying variables that provide a reduced or minimized condition number for a sub-matrix in the lower level model when an additional external constraint is applied. The sub-matrix with the reduced or minimized condition number can correspond to a partitioned portion of the gain matrix that corresponds to unconstrained independent variables and constrained dependent variables.

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.
