摘要
用热重法研究了CO对ZnO脱除H2 S的气氛效应。研究表明 ,在 2 0 0℃～ 2 90℃的温度范围内 ,CO对反应有显著影响。当CO浓度低于 10 %,它可促进反应进行 ,当CO浓度大于 15 %,则会抑制反应进行。O2
Effects of CO on the reaction between zincoxide and hydrogen sulfide were investigated using thermogravimetric analysis (TAG). It was found that in the temperature range of 200℃～290℃, CO had significient effect on this reaction. When the concentration of CO is below 10?%, CO accelerated the reaction, however, when the concentration of CO is up to 15?%, CO inhabited the desulfurization process. The presence of O 2 could avoid the side-reaction of carbon deposition causing by CO.
