Outline of Final Research Achievements

Wood char impregnated with iron liquor (abbreviated as FA), which has been used in vegetable dyeing from old times, was subjected to steam gasification in a fixed bed downdraft reactor. According to obtained results, highly efficient production of hydrogen was realized on the following conditions: preparation of wood char at 500°C, 5 wt % loading of FA as iron metal, gasification at 800°C, total gas (steam plus Ar as carrier) flow of 230mlSTP/cm2・min, and steam partial pressure of 0.4-0.5 for initial sample weight of 0.3 g. It was also shown that FeA as an iron-containing complex did not easily decompose into inorganic iron components to be slightly agglomerated. This must be a real reason for excellent catalytic activity of FeA. In addition, how to efficiently make active FeA was examined.
