Investigation of biomass gasification and fluidization behaviour for pilot double tapered bubbling fluidized bed reactor

The present investigation discusses syngas production through gasification from six different bamboo biomass species available in India's northeast region (Mizoram). The thermochemical conversion of biomass to syngas is accomplished in a novel double-tapered reactor. The pre-processing stage of biomasses includes various shredding, drying, and sieving methods. In the processing stage, the biomass (20 g) is fed to the reactor regularly. The heating element in the interior of the reactor supplies the heat required (600-1000 °C) for the combustion and gasification of biomass samples. The influence of various particle sizes on bed voidage, pressure drop, bed height, suspension density, gas yield, heat transfer, and carbon conversion efficiency is studied. The tapered reactor enhanced the bed hydrodynamics. It is observed that the H and CO composition increases with the temperature (> 900 °C), whereas the CO composition is reduced as a result of the shift reaction. However, the CH yield is enhanced at a temperature (
