Oxygenblown Gasification for Efficient Conversion of Woody Biomass
Oxygen-blown Gasification for Efficient Conversion of Woody Biomass to Liquid Hydrocarbon Fuels Ali T-Raissi, Amit C. Gujar, Jong Baik, Nathaniel Garceau, Errol Hinkamp, Nazim Muradov 2014 Florida Energy Systems Consortium Workshop May 12 -13, 2014 Gainesville, Florida A Research Institute of the University of Central Florida
Rational & Overall Goal The goal of this ongoing activity is to convert solar energy (directly and in combination with that stored in the form of lignocellulosic biomass) to liquid hydrocarbon fuels – as substitutes for petroleum-based fuels (gasoline, jet, diesel).
