A simple and efficient H₂ production procedure from cellulose without emitting CO_x has been developed. In this method, first cellulose and metal hydroxides are ball milled, and then the ball milled mixture is heated under inert and dry atmosphere. The overall reaction can be described in eq 1. Reaction 1 takes place at 400°C to produce the gas containing >93.5% of H₂, 6.4% of CH₄, and 0.1% of CO_x at this temperature. C₆H₁₀O₅ (cellulose) + 6Ca(OH)₂ +0.5Ni(OH)₂ R→CaCO₃ + 11.5H₂ +0.5Ni eq. 1. This is a versatile H2 production method, which can apply to the other organic substances and metal hydroxides. We have found that the ball milling process and addition of Ni(OH)₂ catalyst are required to enhance H₂ yield. In order to achieve the cost/energy efficient H₂ production technology, it is essential to understand the milling effects on the cellulose/hydroxides mixture and the reaction mechanism of hydrogen generation step(s).
