Operation of the TAMU Fluidized Bed Gasifier Using Different Biomass Feedstock

The fluidized bed gasifier (FBG) developed at the Texas A&M University, College Station, Texas was tested using poultry litter, wood chips and cotton gin trash (CGT) as feedstock. The FBG has a diameter of 305 mm and operates at a temperature approximately 760°C (1400°F) and a feeding rate about 70 kg/hr. The synthesis gas produced was analyzed. Preliminary tests showed that the gas quality is lower than the previous runs due to a decrease in hydrogen production.
