Abstract

Laboratory scale agglomeration tests were undertaken to investigate the usability of waste vegetable oil as a bridging liquid in the oil agglomeration for coal cleaning. Waste sunflower oil taken from a university canteen was used as oil in the tests. The effects of the parameters, including coal content, oil content, agitation rate, and agglomeration time on the combustible matter recovery, ash removal, and pyritic sulphur removals, were investigated. It was found that the oil agglomeration process in which waste vegetable oil was used as a bridging liquid succeeded in removal of a considerable amount of ash and pyritic sulphur. Maximum ratios of ash and pyritic sulphur removals were achieved to be 60.63 and 79.09%.
