尾气脱硫新技术实现“治污”“创效”双赢

Core Viewpoint - The research team from Kunming University of Science and Technology has developed a new catalyst with "dynamic shape-selective effect" for the deep removal of sulfur compounds in industrial exhaust gases, achieving a residual sulfur content below five parts per billion, thus providing an innovative and efficient solution for green governance and resource utilization of industrial emissions [1][2]. Group 1: Technological Breakthroughs - The new catalyst utilizes a manganese-doped iron oxide synthesis method, creating a unique "iron-oxygen-manganese" structure that enhances catalytic performance for sulfur compound conversion [2]. - The catalyst demonstrates a removal rate of over 99.99% for typical sulfur compounds such as hydrogen sulfide, methyl mercaptan, and dimethyl sulfide, significantly exceeding current national emission standards [2]. Group 2: Economic and Environmental Impact - The technology allows for the targeted conversion of sulfur compounds into valuable by-products like sulfur, sulfuric acid, or high-purity sulfur, achieving a purity of 99.95% for sulfur, which can be sold as a chemical raw material [2]. - The research team is actively collaborating with multiple chemical enterprises to accelerate the industrial application of this technology, aiming to help companies meet environmental goals while achieving economic benefits [3].
