37.二段液化反応における高分散触媒及び溶媒の役割(石炭利用における科学と工学の接点)

抄録

The liquefaction of three Indonesian coals (South Banko: SBC, Adaro: ADC, Tanitoharum: THC) were performed using carbon-supported FeNi sulfides catalyst with or without tetralin solvent in the single-and two-stage conditions, in order to optimize the combination of catalyst and solvent in the coal liquefaction process. The oil yields in the liquefaction of the three coals were in the order of SBC>ADC>THC regardless of the reaction conditions. 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 by using the equivalent weight of tetralin to coal as a donor solvent.
