9.硫酸鉄系触媒の構造変化とその触媒作用

抄録

Relationships between structure change of iron sulfates and its catalysis were studies in development of highly active iron catalyst for coal hydroliquefaction. Catalytic activities of ferrous sulfate and ferric sulfate on the hydroconversion of 1-methylnaphthalene were very low in the absence of sulfur in the reaction system. But the activities of both sulfates increased with addition of solid sulfur. Ferrous sulfate was easily transformed active pyrrhotite for the aromatic-rings hydrogenation more than ferric sulfate.
