摘要

针对质子交换膜燃料电池（PEMFC）的应用要求，开发了一个包括天然气水蒸气重整、CO变换和变压吸附净化的制氢工艺过程，并着重对重整反应和变压吸附的操作条件进行了实验研究。考察了温度、空速和水碳比对重整反应的影响，得到适宜的工艺操作条件，实验结果表明：温度650℃、水碳比6、空速42h-1时，氢气含量为70.21%，甲烷转化率为77.41%;分析了温度、流速对变压吸附脱除CO效果的影响，结果表明：在0.2MPa、40℃和吸附、脱附时间120s的条件下，产品气中CO浓度接近于1×10-6，经过多次循环后产品气质量稳定，可以连续获得满足80W质子交换膜燃料电池要求的高纯度氢气。

Abstract

To meet the conditions of PEMFC application

a hydrogen production system including natural gas steam reforming

water gas shift reaction and pressure swing adsorption (PSA) purifying process has been developed.The conditions of steam reforming and PSA process were especially studied.The effects of temperature

space velocity and steam to carbon ratio on reforming process were investigated and the optimal process operating conditions were acquired.When temperature was 650℃

steam to carbon ratio was 6 and space velocity was 42 h-1

the hydrogen content in product gas was 70.21% and methane conversion was 77.41%.The effects of temperature and velocity on the PSA process used to remove CO were analyzed.When the pressure was 0.2 MPa

the temperature was 40℃ and the adsorption and desorption time was 120s individually，the CO content in product gas could be lower close to 1×10-6.After rotating several periods

the quality of the product gas was stable.Highly pure hydrogen which satisfies the requirements of 80W PEMFC could be acquired continually.
