Liquefaction of a subbituminous coal with steam and ammonia

Liquefaction of coal with a solvent mixture of steam and ammonia was investigated. Concentrations of ammonia in the solvent mixture ranged from 0 to 30 wt %. Ammonia was found to catalyze the conversion of coal. The highest conversion for a Wyodak subbituminous coal was obtained with 2.5% ammonia at...
