The formation of methane in the reaction of CO and H2O over Rh supported on ZrO2, Al2O3, TiO2, SiO2 and MgO was examined. The high activity was achieved over Rh/ZrO2 and Rh/TiO2 at 300°C and CO dissociation ability of the catalyst was concluded to be an important factor to obtain high activity. At low temperature (c. 200°C), CO was not hydrogenated effectively but CO2 formed by the water gas shift reaction was hydrogenated after the conversion of CO into CO2 was completed. The formation of CH4 appears to occur through the water gas shift reaction, followed by the hydrogenation of carbonaceous species formed by the dissociation of CO or CO2.

Hydrothermal gasification (HTG) experiments were carried out to extract hydrogen from biomass. Although extensive research has been conducted on hydrogen production with HTG, limited research exists on the use of biochar as a raw material. In this study, woodland residues (wood chip) and biochar from wood-chip pyrolysis were used in HTG treatment to generate hydrogen. This research investigated the effect of temperature (300–425 °C) and biomass/water (0.5–10) ratio on gas composition. A higher temperature promoted hydrogen production because the water–gas shift reaction and steam-reforming reaction were promoted with an increase in temperature. The methane concentration was related positively to temperature because of the methanation and hydrogenation reactions. A lower biomass/water ratio promoted hydrogen production but suppressed carbon-monoxide production. Most reactions that produce hydrogen consume water, but water also affects the water–gas shift reaction balance, which decreases the carbon-monoxide concentration. By focusing on the practical application of HTG, we attempted biochar treatment by pyrolysis (temperature of heating part: 700 °C), and syngas was obtained from hydrothermal treatment above 425 °C.
