摘要: ABSTRACTHigh flux tubular membrane reactors were designed for dimethyl ether (DME) steam reforming. Considering the facile scale-up and high of hydrogen, stainless steel supports employed reactors. At 500°C, DME conversion reached ~100%, while hydrogen recovery 20%. However, contamination by CO was rather (>1%), making this process unsuitable proton exchange fuel cell applications, which require a concentration <100 ppm. This result showed that an additional polishing step needed to reduce concentration. Membrane further modified perform water–gas shift reaction on permeate employing fixed bed reactor, yielded high-purity (~99%) along with low content (<20 ppm).
