Abstract

This study investigates the gasification of tea waste biomass in a fluidized bed reactor, with a focus on optimizing syngas composition and energy content. A lab-scale hot flow fluidization bed reactor is designed, fabricated and installed. The impact of fluidization parameters, velocity and gasification temperature on the quality of syngas products is investigated. The effect of these parameters on the CO and H2 percentages and calorific value of the produced syngas is studied. The results show that increasing air injection velocity enhances carbon monoxide (CO) production and reduces carbon dioxide (CO2) levels, with an optimal air injection velocity of 15 m/s for maximizing syngas calorific value. Furthermore, a gasification temperature of around 400 °C is found to be optimal for producing syngas with high calorific value, balancing CO and hydrogen (H2) production while minimizing CO2. A higher CO/CO2 ratio is closely linked to increased syngas energy content, while the methane to hydrogen ratio also influences calorific value, though its impact is less predictable.
