Abstract
AbstractHydrogen is anticipated to become a major source of energy in the future. Hydrogen is a clean burning fuel and has been described as a long‐term replacement for natural gas. It has been demonstrated here that hydrogen can be produced from biomass in the temperature range of 185‐220°C using a single batch reactor pressurised at 25‐30 bar. The current work is based on sugars which are considered here as the biomass resource. Glucose, fructose and sucrose solutions were used for the liquid phase reforming using supported platinum catalyst. The sugar molecules might go through reversible dehydrogenation steps to give adsorbed species on metal sites. This adsorption might be either on CC or CO bond cleavage. Platinum is one of the best catalysts for the reforming of hydrocarbons due to its high selectivity for CC bond cleavage. The CC bond cleavage is the limiting factor for the reforming and leads to a high rate of formation of hydrogen. On the other hand CO bond cleavage results in formation of alcohols, acids and other organic groups.
