Effect of Molten Caustic Leaching on Demineralization and Desulfurization of Asphaltite

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008
Abstract Molten caustic leaching process is effective in reducing significant amounts of ash-forming minerals, pyritic sulfur, and organic sulfur from solid fossil fuels. The effect of leaching asphaltite samples from Seguruk and Harbul collieries of Sirnak and Silopi asphaltite fields (situated in the Southeast Anatolia region of Turkey) with molten ...
