Thermochemical Conversion Of Biomass: A Molecular Viewpoint, Angayle Konstance Vasiliou Jan 2011

Thermochemical Conversion Of Biomass: A Molecular Viewpoint, Angayle Konstance Vasiliou

Chemistry & Biochemistry Graduate Theses & Dissertations (1986-2018)

This dissertation describes experiments performed to study the thermal decomposition of biomass from a molecular viewpoint. The structure of biomass consists of three major parts: cellulose, hemicellulose and lignin. Thermochemical conversion of biomass, specifically pyrolysis and gasification, yields a complex mixture of light gases, condensable vapors and aromatic tars. The goal for the gasification of biomass is to maximize the production of syngas (CO and H2 ) and minimize the production of aromatic tars. This thesis provides thermochemical information particularly related to cellulose decomposition.

The current technology for the conversion of biomass to biofuels is hindered by the lack of fundamental ...
