Methane steam reforming catalyst
WebThese catalytic mixed conducting ceramic membrane reactors are mainly applied in several CH 4 conversion reactions, such as partial oxidation of methane (POM), steam reforming of methane (SRM), dry reforming of methane (DRM), oxidative/nonoxidative coupling of methane (OCM/NCM), and methane aromatization (MA), and bifunctional membrane … WebSteam methane reforming (SMR) accounts for 76% of the dedicated hydrogen worldwide, and will remain the process of choice for large-scale hydrogen production for a long time. Durable and efficient catalysts are always desirable for this high-temperature-preferred process. Here, we report the design of a part
