HYDROGENATION OF UKRAINIAN SALINE COALS - IRON COMPOUNDS AND THEIR TRANSFORMATION DURING HYDROGENATION

Since Ukrainian saline coals contain large amounts of alkaline metals, these cannot be used as a fuel but can be used as a raw material in c oal processing. Hydrogenation of coal is the process in which many gas eous and liquid products are obtained. Some iron compounds originally present in coal can reveal catalytic activity during hydrogention, thu s resulting in a higher yield. Mossbauer effect provides for identific ation of iron minerals and iron compounds in coal and hydrogenation pr oducts. Results of these investigation show that jarosite has catalyti c properties and its presence during hydrogention increased the yield of liquid products.
