✦ Synopsis

The catalytic effect of the mineral matter constituents as estimated in the ash samples prepared from the various specific gravity fractions of a North Assam coal sample on hydrogenation has been studied. Both iron and titanium present in coal have a catalytic effect on hydrogenation. Pyritic as well as organic sulphur present in the coal appear to be responsible for formation of the catalytically active form of iron sulphide from the iron present in the coal mineral matter. Of the aluminosilicates, kaolinite, which is the major component of coal mineral matter, was found to influence the conversion of coal to gas and benzene-soluble products under the conditions of hydrogenation.
