Abstract

A novel membrane reactor system, termed as "one-box," was successfully utilized for hydrogen production from a feed with simulated biomass-derived syngas composition. A CMS membrane was used for the in-situ hydrogen separation. The membrane stability was investigated in the presence of H2S, NH3 and naphthalene and toluene as model tar and organic vapor compounds, in which the membrane proved to be stable at the experimental conditions akin to the WGS reaction environment. The kinetics of the WGS reaction over Co/Mo/Al2O3 catalyst were investigated. The MR performance was examined experimentally for a range of pressures and sweep ratios. Parallel modeling investigations indicated good agreement with the experimental data. The performance of the system was further investigated using the model. The "one-box" shows several advantages over the traditional packed-bed reactor, including improvements in CO conversion and H2 purity, while allowing one to perform the reaction in the presence of H2S, NH3 and being able to deliver a contaminant-free hydrogen product.
