Continuous process for the controlled ozonolysis of organsolv lignin in a solvent consisting of short chain carboxylic acids or short chain carboxylic acid/water mixtures to yield aromatic monomer products including vanillin.
A safe method for the direct oxidation of methane and light alkanes to methanol and other oxygenates is disclosed. Selective catalytic oxidation can be a transformative technology for using increasing abundant natural gas, bio-gas and other sources of low value hydrocarbons via gas to liquid process.
KU researchers have invented a high-pressure reactor equipped with an internal ultrasonic mixer that is useful for preparing nanomaterials and for conducting reactions with ozone and other reactive gases. The apparatus facilitates the use of supercritical carbon dioxide (CO2) as a solvent, allowing the advantages of the solvent properties of the supercritical fluid and the agitation achievable using ultrasonic energy.
This invention provides a method for synthesizing a novel hydrogel that can switch its wettability and absorption for polar liquids and maintain its non-polar liquid repellency while requiring minimal heat input. The invention enables a separation method has the potential to reduce energy costs for some industrial processes and has been employed to separate immiscible polar-non-polar liquid mixtures (water and oil) and a completely miscible liquid mixture (ethanol and heptane) at room temperature.
Method for converting lignin biomass to aromatic compounds using a novel mesoporous acid catalyst.
The current invention is a method for using inexpensive and widely available silica nanoparticles as a fluid loss prevention agent and nanoproppant to maintain micro-fractures during hydraulic fracturing (fracking) to extract oil or natural gas from a variety of geological formations.
KU research has identified combinations of surfactants and polyelectrolyte nanoparticles that improve the stability of CO2 foam for enhanced oil recovery (EOR).
This invention is a novel catalyst made up of a support, a linker, and a ruthenium catalyst nanoparticle. The invention covers not only synthesis of the catalyst but also methods of performing hydrogenolysis with the catalyst.
