Abstract The commonly used dry calcium-based desulfurizers in cement production face issues such as high costs, low desulfurization efficiency, and complex preparation processes. To achieve cost reduction and efficiency improvement, this study explores the use of Ca(OH)2 as a calcium-based desulfurizer substrate, fully simulating industrial flue gas containing SO2. Experiments were conducted to investigate the effects of specific surface area of the desulfurizer, as well as the incorporation of active components, catalytic components, and industrial mineral powders on desulfurization performance. A novel dry desulfurizer was developed by doping industrial mineral powder. The results indicate that the newly developed dry desulfurizer, which incorporates 15% amino-based active substances, 5% ilmenite, and 5% barite into Ca(OH)2, exhibits significant desulfurization efficacy. Industrial application validation has shown that this desulfurizer achieves a desulfurization efficiency of over 90%, with no by-product emissions and low cost, thereby presenting broad market application prospects.
