• 7-3-1 Resolving solution interface reaction of pyrite during oil agglomeration for developing desulfurization and coal cleaning efficiency

抄録

Recently the large amounts of waste fine coals are produced, which are difficult to be treated because of the high ash contents and inorganic sulfuric compounds. In order to make efficient use of waste fine coal, the retrieval technique is necessary for recovery of combustible contents from fine waste coals. Nowadays oil agglomeration process can deal with these problems. In this study, we investigated the mechanism of solution interface reaction on oil agglomeration in order to separate pyrite sulfur effectively from waste fine coal. During the high basic condition, pyrite sulfur reduction indicated high values since the pyrite surface became hydrophilic due to covering surface of pyrite sulfur by ferric hydroxide. As the results, we can remove pyrite under high basic condition, however decrease of coal cleaning efficiency occurred at this condition.
