Desulfurization of Donetsk Basin coals by air-steam mixture

Abstract The process of coal desulfurization by processing with air-steam mixture at 623–673 K was investigated. Three coals of different rank (high- and low-volatile bituminous and anthracite) and sulfur content were used. The degree of desulfurization of the coals was 58.2, 79.8 and 81.4% respectively, and the degree of pyritic sulfur removal 96.8, 98.4 and 99.4% respectively.
