DR. HANWU LEI Biofuels, Bioproducts & Thermochemical Catalysis Lab

Research Interests

  • Novel process and technology development for biofuels and bioproducts: Jet fuels, phenols, aromatics, cycloalkanes, hydrocarbons, hydrogen, syngas, biochar, activated carbon, nanocarbon, nanocarbon catalysts, and CO2 capture
  • Biomass thermochemical conversions (torrefaction, pyrolysis, microwave pyrolysis, hydrothermal liquefaction, organosolv liquefaction)
  • Fundamental studies and development of carbon based catalysts and zeolite based catalysts in catalytic processes, bio-oil upgrading, and biochar and nanocarbon utilization for fuels, bioproducts, and chemicals production
  • Process development and energy recapture from co-feeding of lignocellulosic biomass with polymers waste (e.g. waste plastics and tires) in catalytic pyrolysis and catalysis for aromatics, cycloalkanes, and jet fuels
  • Biomass hydrothermal pretreatment, biomass clean fractionation (hemicelluloses, cellulose, and lignin), protein separation, and oil extraction
  • Fundamental studies and development of biomass conversion pathways, kinetics, mechanism, and techno-economic analysis
  • Bioprocess engineering
  • Renewable energy technologies

New positive synergy was developed in Dr. Lei’s Group for aromatics from catalytic microwave co-pyrolysis of biomass and waste plastics, resulting in jet fuels containing 31% of paraffins, 53% of cycloalkanes, and 15% aromatic hydrocarbons, which were consistent with those fuel components in JP-5 and commercial Jet A
