Energy and environment are expected to be the main challenges of the human life in the long term future. Biomass as a renewable source of energy has been of the great interest especially in the last decade. Hydrogen as a clean fuel can take a significant role in providing a better environment and sustainable development. Supercritical water gasification (SCWG) is a promising technology for hydrogen production from organic wastes. In this study, the effects of reaction time on gas yield, gas composition and carbon gasification efficiency (CGE) were investigated. Experiments were carried out in a batch stainless steel 316 reactor at the temperature of 400 °C and feed concentration of 9 wt%. Sugarcane bagasse was partially gasified in supercritical water (SCW) and a gas containing hydrogen, methane, carbon monoxide and carbon dioxide was produced. CGE of 18.7% was achieved after 105 minutes of reaction time. Increase in pressure up to 45 MPa could not improve the gasification efficiency. Higher gasification efficiency could be achieved by either catalyst or higher temperature.
