Abstract
The new approach to produce hydrogen from sewage sludge biomass is proposed in this work. It is known that hydrogen generation occurs with heating the mixed sample of sewage sludge with additives of hydroxide nickel and calcium. Here, detailed experiments with various added amounts of both hydroxides have been conducted and hydrogen yields have been obtained. As a result, with both raw and dried sewage sludge samples, at less addition of nickel hydroxide, hydrogen yields increase with the less addition of calcium hydroxide. These results suggesting it is possible to produce hydrogen at relatively low cost by decreasing addition of both hydroxides.
