We present here a study of the water gas shift membrane reactor (WGS-MR) in the context of its potential application in the IGCC process for power generation from coal. In our research, we use in the WGS-MR a sour-shift WGS catalyst and carbon molecular sieve (CMS) membranes, and show that the reactor displays higher conversions than a conventional packed-bed reactor (PBR) under the IGCC-relevant conditions, i.e., for temperatures up to 300 °C and pressures up to 25 bar. Our experimental results manifest the ability of the WGS-MR to operate under the desired conditions and to improve the efficiency of the WGS reaction. They demonstrate, in addition, the potential of the MR to carry out the in-situ separation of hydrogen using the CMS membranes. We conclude from our study, that the CMS-membrane-based WGS-MR is a good candidate technology for incorporation into IGCC power plants for environmentally-benign power generation.

我们在此对水煤气变换膜反应器(WGS-MR)进行的研究进行了研究,并将其潜在地应用于IGCC制煤发电过程中。在我们的研究中,我们在WGS-MR中使用了酸移WGS催化剂和碳分子筛(CMS)膜,并表明在IGCC相关条件下,该反应器显示出比常规填充床反应器(PBR)更高的转化率即温度最高为300°C,压力最高为25 bar。我们的实验结果表明,WGS-MR具有在所需条件下运行并提高WGS反应效率的能力。他们还证明了使用CMS膜进行MR进行氢气原位分离的潜力。我们从研究中得出结论,
