Project Overview
Austin, TX SWST/FPS International Conference June 9, 2013
• Thermochemical Characterization
– Proximate
– Ultimate
– Gasification
• Silvicultural Regimes

Conclusions
• Proximate/Ultimate Analyses– Silviculture and Feedstocks are Significantly
Different
• Gasification – Variability of Test Conditions Affect Results
– Does Appear That Syngas Composition is a Function of Feedstock
• Very Early Stages in Syngas Analysis
