ResumoCoal/CaO powder mixtures were continuously supplied into a reactor to react with steam at high pressure and high temperature. At 923 K and 5.0 MPa, the gas produced from the reaction of Taiheiyo coal/CaO with steam consisted of mainly H2, with smaller amounts of CH4, C2H4, C2H6 and CO2. Increasing the pressure enhanced H2 production and CH4 decomposition. Above 3 MPa, the gas from the reaction contained Taiheiyo>Wyoming. The Wyoming and Datong coals produced less H2 than the Taiheiyo coal.
