Iron oxide dry desulphurization is an effective method for H2S removal. In this paper, three limonite materials from Yeshan, Xinqiao and Shao jilao iron mines were selected as desulfurizers for hydrogen sulfide removal. The effects of calcination temperature and reaction temperature on the desulfurization performance of limonite were investigated at medium-high temperatures, and a desulfurization cycle regeneration experiment was conducted. The removal mechanism of hydrogen sulfide was analyzed by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. The results show that SJL-300 as an effective desulfurizer has a total desulfurization capacity of 1 525.7mg/g after seven cycles. In the evolution process of the reaction between limonite and hydrogen sulfide, pyrite and pyrrhotite are the desulfurization products at 300-400 ℃, while only pyrrhotite appears at > 500 ℃.

煤气化、液化等利用过程都需要对工艺气体中硫化氢进行高温脱硫,廉价、高效脱硫材料一直是本领域探索研究的热点。褐铁矿是难选难利用铁矿资源,未得到有效利用。选取叶山、新桥、筲箕涝不同成因类型的褐铁矿作为脱硫剂,考察了煅烧温度以及脱硫反应温度对硫化氢脱除性能的影响,并进行了脱硫循环再生实验。采用X射线衍射、扫描电子显微镜、X射线光电子能谱等技术表征3种褐铁矿及其脱硫产物矿物学特征,探究褐铁矿脱除硫化氢的机理。结果表明:筲箕涝褐铁矿煅烧产物脱硫性能较优,7次再生后总脱硫容量达到1 525.7 mg/g,是一种具有稳定脱硫容量且可多次再生的脱硫剂。SJL-300与硫化氢反应物相演变途径为:在300~400 ℃区间反应产物为低结晶度黄铁矿和磁黄铁矿;500 ℃以上产物只有磁黄铁矿。

煤气化、液化等利用过程都需要对工艺气体中硫化氢进行高温脱硫,廉价、高效脱硫材料一直是本领域探索研究的热点。褐铁矿是难选难利用铁矿资源,未得到有效利用。选取叶山、新桥、筲箕涝不同成因类型的褐铁矿作为脱硫剂,考察了煅烧温度以及脱硫反应温度对硫化氢脱除性能的影响,并进行了脱硫循环再生实验。采用X射线衍射、扫描电子显微镜、X射线光电子能谱等技术表征3种褐铁矿及其脱硫产物矿物学特征,探究褐铁矿脱除硫化氢的机理。结果表明:筲箕涝褐铁矿煅烧产物脱硫性能较优,7次再生后总脱硫容量达到1 525.7 mg/g,是一种具有稳定脱硫容量且可多次再生的脱硫剂。SJL-300与硫化氢反应物相演变途径为:在300~400 ℃区间反应产物为低结晶度黄铁矿和磁黄铁矿;500 ℃以上产物只有磁黄铁矿。

Iron oxide dry desulphurization is an effective method for H2S removal. In this paper, three limonite materials from Yeshan, Xinqiao and Shao jilao iron mines were selected as desulfurizers for hydrogen sulfide removal. The effects of calcination temperature and reaction temperature on the desulfurization performance of limonite were investigated at medium-high temperatures, and a desulfurization cycle regeneration experiment was conducted. The removal mechanism of hydrogen sulfide was analyzed by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. The results show that SJL-300 as an effective desulfurizer has a total desulfurization capacity of 1 525.7mg/g after seven cycles. In the evolution process of the reaction between limonite and hydrogen sulfide, pyrite and pyrrhotite are the desulfurization products at 300-400 ℃, while only pyrrhotite appears at > 500 ℃.
