Abstract: In an embodiment is provided a process to re-refine used oil that includes introducing a used oil and a solvent to a separation unit under separation conditions selected to produce a purified oil product, the separation unit comprising a porous membrane, a semiporous membrane, or both; and separating the used oil to obtain an effluent comprising a purified oil product. In another embodiment is provided an apparatus for re-refining used oil that includes a separation unit comprising a porous or semiporous membrane; a used oil feed coupled to an inlet of the separation unit; and an inlet of a diffusate collection unit coupled to an outlet of the separation unit. In another embodiment is provided a composition generated from a membrane separation process that includes a base oil, the composition having a soot content of about 0.05% or less.

Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

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: The present disclosure relates to methods for compositional analysis of algal biomass, specifically weight percent elemental composition. In at least one embodiment, a method for compositional analysis of an algae sample includes flash combusting a first portion of the algae sample to provide a carbon wt %, a hydrogen wt %, and a nitrogen weight %. The method includes pyrolysing a second portion of the algae sample to provide an oxygen wt %. The method includes scanning a third portion of the algae sample using x-ray fluorescence to provide an elemental intensity. The method includes normalizing the elemental intensity using the carbon wt %, the hydrogen wt %, the nitrogen wt %, and/or the oxygen wt %.
