Abstract

The invention provides a coal additive. The coal additive comprises an emulsifier, a dispersant, a corrosion inhibitor and a penetrant. The coal additive contains O, Mg, Al, Si, S, Ca, Ba and Mn. The coal additive has the advantages that the emulsifier, the dispersant, the corrosion inhibitor and the penetrant are used and the rare earth elements improve catalyst activity so that a traditional exterior-to-interior combustion mode is changed into an interior-exterior synchronous combustion mode and thus a coal complete-combustion degree is improved and a heat loss caused by chemical incomplete combustion and mechanical incomplete combustion of coal in a furnace is reduced; and through composite carriers having mesoporous structures, catalyst activity is improved, a hydrodesulfurization process is finished and discharge amounts of flue dust and harmful gas in exhaust gas are reduced so that coal saving and sulfur fixation are realized.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a coal additive. Background technique [0002] As we all know, the quality of coal directly affects the combustion of the boiler, so coal additives are usually added to the coal quality, and coal additives are put into the boiler combustion equipment to fully burn the combustibles in the coal. Generally speaking, natural activated carbon is used as a coal catalyst product, and natural activated carbon is originally produced in South Africa with blue sea and blue sky. [0003] Natural activated carbon can greatly improve the combustion efficiency of various coal-fired boilers, reduce the consumption of coal and alternative fuels, reduce various emissions that pollute the atmosphere, and greatly reduce boiler residues, thereby reducing boiler maintenance times and saving enterprises cost and reduce pollution for the environment. However, at present, the cost of natural active c...
