57.鉄系炭素微粒子担持触媒へのNi及びMo添加による石炭液化活性の向上

抄録

The liquefaction of two Indonesian coals (Adaro: ADC, Tanitoharum: THC) was performed using carbon-supported FeNi, NiMo, and FeMoNi sulfides catalyst with tetralin solvent in the single-stage (450℃-60min) conditions, in order to optimize the combination of active metals for the improvement of catalytic activity. Fe-Ni/Ketjen Black (KB) catalyst exhibited the lower activity for the hydrogenation of aromatics and coal liquefaction without solvent, however, it gave the similar oil yields to those with NiMo/KB catalyst with the equivalent weight of tetralin to coal as a donor solvent. The addition of Mo (2 or 3wt%) to FeNi sulfide supported on KB improved the liquefaction acivity as well as the hydrogenation activity with the lower loading of Ni (2 or 3wt%).
