Artigo:

This work aimed at comparing the gasification potential of rice husk samples from Brazil (CAZ1) and Thailand (CAZ2). The pyrolysis step was performed in two pyrolysis reactors under different conditions. The product yields were determined and related to the pyrolysis conditions applied. The biomass and rice husk chars were characterized and overall char combustion and gasification reactivities were measured by thermogravimetry in synthetic air and in CO2, respectively. The differences in samples properties play important roles in the thermochemical conversion steps. These differences may reflect local variations of the agricultural growing conditions, as noticed between the two rice husk samples studied, being the Thai rice husk char more reactive than the Brazilian one both in air and CO2 gasification.
