| Abstract Scope |
Innovative nanomaterials for membranes or sorbents are enablers to advance separations technologies that can meet the performance and cost targets ensuring the carbon/hydrogen/energy efficiency-dependent bioeconomy. Recovery of biooil and water-soluble oxygenated hydrocarbon molecules and targeted removal of impurities (such as carbonyl molecules or nitrogen compounds) are critical to biorefineries. Molecular separations of liquid or vapor mixtures require the nanoscale control of material structures and the tailoring of surface/interfacial functionality chemistry. In this work, surface-engineered (superhydrophobic) nanoporous inorganic membranes were developed to provide several orders of magnitude higher flux in phase separation of biooil-water emulsions. On the other hand, novel ceramic-polymer hybrid materials with/without composited nanoparticles (such as graphene oxide or covalent organic frameworks) are being developed to dewater and concentrate the aqueous solutions that contain oxygenated hydrocarbon molecules (such as carboxylic acid from thermochemical conversion pathways or 2,3-butanediol from biochemical fermentation pathway), desalination, or organic solvent separations. |
