Abstract

Abstract:

Aiming at the environmental protection problem of sulfur dioxide exceeding the standard caused by the use of solid waste and hazardous waste in cement industry,a new type of high efficient catalytic desulfurizer was prepared by screening ferric oxide and magnesium oxide with catalytic effect through desulfurization experiment,and its desulfurization efficiency was higher than that of industrial grade calcium hydroxide.The industrial application in DD cement enterprise in Henan Province showed that compared with industrial grade calcium hydroxide,the new catalyst had higher desulfurization efficien-cy,and the ratio of Ca/S was reduced by 56.7%.Through the use of new efficient catalytic desulfurizer,cement enterprises could meet the ultra-low emission requirements of ρ（SO₂）<35 mg/Nm³,and there was no waste in this process,which had broad application prospects.

Key words: high efficiency catalytic desulfurization, cement, sulfur dioxide, ultra-low emission
