摘要：A method of producing a solid secondary raw material that contains calciumsulfate, comprising mixing a waste hydrocarbon with at least one of a waste sulfuric acidand acid waste sulfuric-acid derivative, and combining the mixture with enough poweredlimestone or fly ash containing calcium carbonate to ensure that the reaction product willsolidify by itself, and with at least enough water to ensure the hydration of the formedcalcium sulfate. The product is useful in making Portland cement clinker, or in furnace asa fuel and/or a desulfurization additive.
