Biomass pyrolysis is emerging as a key element of the sustainable energy future.  Conversion of lignocellulocic matter from woody plants, is among the most promising routes.  To study the conversion of woody materials to gas, oil and char, TTU researchers have developed a novel method for producing near perfect tiny biomass spheres.  Modeling temperature and mass changes for a single sphere is an important step in understanding how pyrolysis works.  This key information will allow for a better understanding of biomass pyrolysis conversion mechanisms as well as how to best design and optimize equipment and particle milling technologies.  Ascertaining the velocity profile of the carrier gas is an important step in accomplishing the temperature distribution, as having an accurate position of the particle as it is pushed through the reactor by the carrier gas will allow for a correct prediction of conversion.  A continuum-based model is being developed to track the temperature, reaction, and position of a single particle through a known temperature field.  The results will be compared to experimental data and used to predict effects of scale for reactor design.
