This study uses AspenTech software (V12) to model and simulate biohydrogen production from sugarcane bagasse, covering gasification, hydrogen enrichment, and purification stages. This integrated approach, starting from raw biomass to achieving over 99% hydrogen purity, is not well-explored in the literature. In gasification, a steam-blown fluidized bed gasifier produces product gas. Sensitivity analysis shows that higher temperatures enhance H₂ production, while higher pressures reduce it. Increased steam injection and moisture content also boost H₂ output. The product gas then undergoes hydrogen enrichment process, with water gas shift (WGS) reaction increasing hydrogen concentration by 9.1%. Higher WGS reactor temperatures decrease CO conversion, reducing H₂ levels, while high-temperature steam injection and increased steam flow enhance H₂ production. Finally, pressure swing adsorption purifies the synthesis gas to over 99% hydrogen. Higher feed rates accelerate breakthrough, and higher adsorption pressures delay it. Future optimization should focus on efficiency and environmental impact, considering various biomass traits.
