Conversion of Coal over an Oxide Catalyst Produced from Natural High-Magnesia Siderite

Resumo

The conversion of coal and coal tar over iron–magnesium oxide catalyst produced from natural high-magnesia siderite is investigated. The use of this catalyst in the thermal processing of coal tar increases the yield of lighter fractions (by factors as large as 1.7) and decreases the yield of heavier fractions (by factors as large as 1.8). The catalytic pyrolysis of coal increases the total yield of the lightest materials (by a factor of 1.1–2.3). The nonmagnetic fraction of the solid residue may be added to coking batch, while the magnetic fraction may be used in sintering.
