本项目结合当前我国工业气及多种过程废气的脱硫净化与硫磺资源化回收的实际应用需求，在前期工作基础上，采用我国丰产元素钨、钼的多元杂多化合物及其对应的离子液体为脱硫主剂，辅配以必要的活性催化组分对其脱硫及再生性能进行调变。分别采用水溶液和绿色溶剂－离子液体构建并优选出分别适于常温和高温（150-250℃）的气体脱硫且均能同时回收硫磺的绿色可再生液相氧化脱硫新体系。在此基础上，通过系统、深入的宏观反应动力学及过程机理研究，为实现天然气、焦炉煤气、半水煤气等工业气体的脱硫精制与硫资源回收以及多种过程废气的脱硫净化奠定工业应用基础。

In response to the national practical needs in H2S removal and sulfur recovery from industrial and waste gases and based on the preliminary research of the applicants, this proposal outlined an effective and economical method of H2S removal and sulfur recovery using the heteropoly compounds(HPC) of the so-called rich elements of W and Mo of China as main desulfurizers, in forms of both inorganic acids and their corresponding ionic liquids, with the addition of catalytic species, if necessary, to adjust the activity of the main desulfurizer. Using water and ionic liquid as green solvents, new liquid redox scrubbers of HPC will be formulated, which are suitable for H2S removal and sulfur recovery at ambient and high temperatures, e.g. 150-250 C. Furthermore, researches concerning the relevant mechanisms governing the redox process as well as the macro-kinetic behavior of the overall process will be conducted. The outcome of the results from this project will lay a solid foundation for its further application in H2S removal and sulfur recovery from the purification of industrial gases, such as natural gas, coke oven gas, and semi-water gas, as well as exhaust gases from other processes.
