摘要：This research investigates the gasification of hydrothermal-carbonized-biomass pellets, focusing on the synergistic impact of pellets size and moisture content on the production of hydrogen, methane, and carbon monoxide. The study employs a two-dimensional Eulerian approach to elucidate the intricate relationships between these two critical parameters and their combined impact on gasification efficiency. The impact of moisture content and pellets size on reaction kinetics and heat transfer are explored to unravel the underlying mechanisms governing gasification of biomass for high yield combustible gases. In all four pellets size examined in the current study (5, 10, 15, and 20mm), the lowest pellets size increased the cold gas, carbon conversion and gasification efficiency by 10.78, 23.03, and 21.6% respectively as compare to the highest pellets size. The results also revealed a retrogressive decline of 61.6%, 59.6%, 42.1%, and 35.2% for moisture contents of 4.3%, 7.8%, 11.0%, and 14.5%, respectively for the gasification efficiency. ? 2024, The Authors.
