Abstract

In this study
response surface methodology (RSM) with Box-Behnken design (BBD) was used to
evaluate the effects of process parameters of reaction time, initial water
volume, amount of feedstock and amount of catalyst on total gasification and
hydrogen production yield by low temperature hydrothermal gasification of Sorghum
biomass at 250°C. Ruthenium (III) chloride was used as a catalyst in catalytic
runs. Significances of the main and interacting effects of independent
parameters were determined by ANOVA. Numerical optimization was used to
optimize the process parameters for maximum yield hydrogen production. The
optimum conditions for maximum hydrogen production were determined as a residence
time of 58.6 min, water volume of 24.5 mL and catalyst amount of 0.02g.
