Experiments were conducted to investigate the reforming of organic compounds (primarily methanol) in supercritical water at 550.degree. C.-700.degree. C. and 27.6 MPa in a tubular Inconel.RTM. 625 reactor. The results show that methanol can be completely converted to a product stream that is low in methane and near the equilibrium composition of hydrogen, carbon monoxide, and carbon dioxide. The effect of reactor temperature, feed concentration of methanol, and residence time on both conversion and product gas composition are presented.
