摘要

利用电化学溶解-沉淀法回收利用硫化氢制取氢气和硫化锌.考察了不同硫化氢含量、进气流速对吸收反应的影响，并对电解制氢和硫化氢吸收反应的双系统匹配运转进行了详细研究.结果表明，在温度为25℃、搅拌速率为100 r8226;min-1条件下，硫化氢的一次吸收率可达99.9%以上，电解液可循环使用;电解反应可在低电压0.5 V和25℃条件下进行，制氢电耗低于1.2 kW8226;h8226;m-3H2.

Abstract

A new technique of producing H2 and ZnS from H2S was studied with the electrochemical dissolution-precipitation method. The results showed that in the absorption reactor

where the temperature was 25～30℃

and the rate of stirring was 100 r8226;min-1

the absorption rate of hydrogen sulfide (5%～100%) in one processing could reach 99.9% and high quality of zinc sulfide could be obtained. At the same time

in the electrolysis reactor

pure hydrogen could be obtained under the temperature 25～30℃

electricity voltage 0.5 V and electricity consumption 1.2 kW8226;h8226;m-3H2.
