黄磷尾气中的含硫气体（H2S、COS和CS2）是影响碳一化工的有害物质，实现黄磷尾气资源化必须脱除其中的H2S、COS和CS2。由于黄磷尾气组分的复杂性和特殊性，对于黄磷尾气这种强还原气氛下三种含硫气体同时脱除的研究未见报道。本项目根据黄磷尾气的特征，采用生物炭载体催化剂同时脱除其中的H2S、COS和CS2，系统研究生物炭载体表面的物理化学特性、载体结构等对催化剂性能的影响；针对新的反应体系和反应条件，深入研究活性物质分布对脱硫性能的影响规律；开发新型生物炭载体催化剂，解决在不吸附活化黄磷尾气中CO的条件下，同时去除H2S、COS和CS2杂质的关键科学问题；并提出生物炭载体催化剂同时脱除H2S、COS和CS2的反应机理。项目符合当前国家、行业、地方废气净化控制技术的需求，有利于拓展和深化新型脱硫材料的研究内涵，为黄磷尾气中含硫气体的同时净化及黄磷尾气的资源化利用提供理论依据和技术方法。

H2S, COS and CS2 of yellow phosphorus tail gas are harmful gases which can affect the C1 (one carbon) chemical industry. If yellow phosphorus tail gas can be used as raw material gas to synthesize chemically product, removal of H2S, COS and CS2 are need. Simultaneous removal of H2S, COS and CS2 under the condition of strong reducing atmosphere has not reported due to the complexity and particularity of yellow phosphorus tail gas. According to the characteristics of yellow phosphorus tail gas, the H2S, COS and CS2 can be simultaneous removed with biochar carrier catalysts. The effect of physicochemical characteristics and structure of carrier on activities of catalysts are studied systematically. The distribution of active components is also discussed according to the new reaction system and reaction conditions. Based on these studies, the new biochar carrier catalysts are developed, the key scientific issues for simultaneous removal of H2S, COS and CS2 at yellow phosphorus tail gas atmosphere can be solved, and CO is not adsorbed as well. Meanwhile the mechanism of simultaneous removal of H2S, COS and CS2 with biochar carrier catalysts is also investigated. The project is in line with the national, industry and local needs of waste gas purification control technology currently. The formation of systems theory is beneficial to expand and deepen the connotation of new desulfurization materials, which provide a theoretical and technical approach for studying application of simultaneous removal of H2S, COS and CS2 and utilization of yellow phosphorus tail gas.
