摘要

为消除气体中硫化氢对人类及生态环境的危害和对工业生产的影响，提出用氢氧化铁（亚铁）的“醋酸─醋酸钠（钾）－氨”的缓冲水溶液，在对苯二酚或水杨酸的催化下，脱除气体中的硫化氢、少量二氧化碳和部分氧气；脱硫液自动再生，产生单质硫.脱硫后气体中硫化氢含量可降至1.52mg·m~(-3)以下，成本低，操作稳定，腐蚀轻，无环境污染．同时，建立了相应的数学模型，经实验验证，实验结果与数学模型基本符合．

Abstract

In order to more efficiently eliminating the harm of hydrogen sulfurides to human being and ecological environment and industries

we have put forward a new method for desulfurizing

partially decar-bonizing and deoxidating of gases with a buffering solution of“acetic acid─sodium(potassium) acetate-ammonia”containing Fe~(2+) and Fe~(3+)

and the buffering solution is automatically regenerated catalyzed by p-dihydroxy-benzene or salicylic acid.Meanwhile

the mathematical models have been established and satisfactorily supported by experimental data.
