ELEMENTAL SULFUR FORMATION IN THE MEYERS COAL DESULFURIZATION PROCESS

Abstract

The rate of formation of elemental sulfur on the surface of lignite particles during leaching by acidic ferric chloride was found to depend on the concentration and acidity of the ferric chloride, the particle size of the sample, the temperature and the rate of stirring. Generally, S formation increased during the first 40-45 min of leaching and subsequently decreases. It was more significant with small particles and high acidities.
