Experimental study on the paper sludge reusing as a coal desulfurizer

This paper describes the reutilization of paper sludge, a kind of industrial solid wastes, for preparation of a coal desulfurizer. Studies include experiments on paper sludge single component and paper sludge-fly ash composite components reusing as a coal desulfurizers. When the paper sludge used as a single component of the calcium-based coal desulfurizer, the desulfurization rate was more than 80%. When paper sludge blending 40% fly ash as a desulfurizer and the desulfurizer admixture up to the amount of 15% the desulfurization rate was more than 95% In addition, after adding fly ash into paper sludge, the specific resistance of the sludge decreased 70% and the dehydration property of the sludge improved a lot.
