Abstract

The results of studying the samples of efficient sorbents based on domestic natural raw materials, namely, ferromanganese nodules (FMNs) are presented. The use of these sorbents has significant potential for solving the pressing problem of environmental protection, such as the purification of gas flows from toxic sulfur compounds. The influence of the calcination temperature of sorbents on their physicochemical and sorption characteristics is studied. It is shown that the calcination temperature of a sorbent significantly affects its sorption capacity with respect to hydrogen sulfide, and optimal sorption characteristics are exhibited by the sorbent calcined at 300°C. SEM elemental mapping and DRIFT study results for spent samples allowed us to propose a temperature-dependent pathway of hydrogen sulfide sorption on the synthesized sorbents.

基于铁锰氧化物的气体排放脱硫吸附剂的开发与研究

介绍了利用国产天然原料锰铁结核制备高效吸附剂样品的研究结果。这些吸附剂的使用对于解决环境保护的紧迫问题具有巨大的潜力，例如从有毒硫化合物中净化气流。研究了吸附剂的煅烧温度对其物理化学特性和吸附特性的影响。结果表明，吸附剂的煅烧温度对其对硫化氢的吸附能力有显著影响，在300℃煅烧时吸附剂表现出最佳的吸附特性。废样品的SEM元素映射和DRIFT研究结果使我们提出了硫化氢在合成吸附剂上吸附的温度依赖途径。
