空速和二氧化碳对沼气脱硫剂硫容确定的影响

为了弄清空速与二氧化碳含量对氧化铁脱硫剂硫容确定的影响,分别在实验气源为纯硫化氢,空速为40、80、120和160 h-1以及实验气源为二氧化碳含量分别在0%、20%、40%和80%,其余为硫化氢,空速为80 h-1条件下,对T502(粗脱硫剂)和HXT-2(精脱硫剂)2种氧化铁脱硫剂进行了不同测试条件对氧化铁硫容确定影响的研究。研究结果表明,T502和HXT-2氧化铁脱硫剂硫容测试结果随着空速和二氧化碳含量增加而减少,结果显示了在空速较低条件下(120h-1),二氧化碳含量在40%以下时对氧化铁脱硫剂硫容测试结果影响不大,但二氧化碳含量在40%以上时,对氧化铁脱硫剂硫容测试结果影响显著。

Effects of different test gas speeds and CO2 contents on sulfur capacity determination of biogas desulfurizer

In this study, the effects of different test gas speeds and carbon dioxide (CO₂) contents on sulfur capacity determination of ferric oxide (Fe₂O₃) biogas desulfurizer were investigated. With pure hydrogen sulfide (H₂S) as test gas source, reseach on the sulfur capacity determinations of Fe₂O₃ biogas desulfurizer T502 (crude desulfurization agent) and HXT-2 (fine desulfurization agent) was carried out, when the test gas speeds were 40 h^-1, 80 h^-1, 120 h^-1 and 160 h^-1, and the CO₂ contents were 0%, 20%, 40% and 80% respectively with the test gas speed of 80 h^-1. Results showed that sulfur capacity determinations of T502 and HXT-2 Fe₂O₃ biogas desulfurizer decreased with the increasing of the test gas speed and CO₂ content. Furthermore, with the lower test gas speed (<120 h^-1), low CO₂ content (< 40%) had little effect on the sulfur capacity determinations of T502 and HXT-2 Fe₂O₃ biogas desulfurizer, while the effect was remarkable with high CO₂ content (>40%).
