Abstract:
This study presents the validation and optimization of a 20.kWth spouted bed reactor designed for hydrogen production from biomass, focusing on thermochemical conversion of wood pellets as a model feedstock. Reactor modifications on the original set up included redesign of the feeding and exhaust systems to improve operational stability. A series of gasification experiments were conducted by varying key parameters: equivalence ratio (ER), air inflow rates (affecting residence time), and reaction duration. Results show that decreasing ER and increasing residence time enhance hydrogen and carbon monoxide yields, with hydrogen concentration reaching up to 9.8% vol—significantly higher than in previous studies on the same plant. The study confirms the improved performance of the modified reactor and highlights its potential for future applications with agricultural and textile waste.
