Cellulosic Bioenergy Research: Chemical Conversion
Dr. Lance Lobban is director, Francis W. Winn Chair and professor in the University of Oklahoma's School of Chemical, Biological and Materials Engineering. He is also the co-principal investigator of the multidisciplinary, multi-institutional, five-year NFS EPSCoR Research Infrastructure Improvement Plan entitled “Building Oklahoma’s Leadership Role in Cellulosic Bioenergy."
Dr. Lobban's research focuses on catalysis and reaction engineering. His research group combines experimental measurement with theoretical analyses of reaction mechanisms in order to better understand and improve catalytic processes.
The operating conditions of the reacting systems that Dr. Lobban and his co-researchers have studied include gas phase reactions at temperatures up to 800°C, liquid phase reactions at room temperature and below, and reactions in presence of a strong electric field. The experimental techniques include steady and unsteady (transient) state kinetics measurements, adsorbed species identification using diffuse reflectance Fourier transform infrared spectroscopy and measurement of isotopic species using mass spectrometry.
One of Dr. Lobban's current research projects is an investigation of methane oxidative coupling under a variety of conditions including cold plasma conditions and on different catalysts.
A second project involves the synthesis and use of novel TiO2 aerogels and binary SiO2-TiO2 aerogels as photocatalysts. The unique properties of these aerogels are hypothesized to allow more efficient use of UV light to activate the photocatalysts for the complete oxidation of air and water contaminants.
A third active project examines the fundamentals and applications of catalysis by adsorbed surfactant aggregates. Potential applications include selective production of valuable chemicals and hazardous waste detoxification.
