摘　　要：硫化氢是一种应用非常广泛的特种气体,制备高纯度的硫化氢具有重要的经济效益和环境效益。硫化氢中含有的微量二氧化硫对硫化氢下游产品的开发应用产生严重的不利影响,必须予以脱除。介绍了还原法、吸附法等二氧化硫脱除技术的原理、特点以及研究现状。Hydrogen sulfide is a very wide range of special gas,purification and purification of high purity hydrogen sulfide has important economic benefits and environmental benefits. Trace sulfur dioxide contained in hydrogen sulfide has a serious negative impact on the development and application of hydrogen sulfide downstream products,and therefore must be removed. This paper introduces the principle,characteristics and current situation of the reduction method,adsorption method and so on.
