摘要

中国天然纯碱（NSA）储量丰富，生产成本低廉，是各种化工行业的关键材料。本研究介绍了两种创新的改性技术--物理混合和表面涂覆硅酸钠溶液（SSS）--以提高天然纯碱脱硫剂的抗吸湿性和分散性。实验结果表明，这两种方法都能显著减少由湿气引起的结块，10 wt% SSS 改性的 NSA 能达到最佳脱硫性能。这种改善归功于硅酸盐保护膜的形成，它增强了流动性和防潮性，使其非常适合烟气脱硫的工业应用。

Study on modification and performance of desulfurizer produced by natural soda ash

China’s extensive natural soda ash (NSA) reserves and cost-effective production make it a key material in various chemical industries. This study introduces two innovative modification techniques—physical blending and surface coating with sodium silicate solution (SSS)—to enhance the hygroscopic resistance and dispersibility of NSA desulfurizers. Experimental results indicate that both methods significantly reduce moisture-induced agglomeration, with the 10 wt% SSS-modified NSA achieving optimal desulfurization performance. This improvement is attributed to the formation of a protective silicate film, which enhances flowability and moisture resistance, making it highly suitable for industrial applications in flue gas desulfurization.
