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