Catalytic partial oxidation of methane rich mixtures in non-adiabatic monolith reactors

Stable Rh particles in hydrotalcite-derived catalysts coated on FeCrAlloy foams by electrosynthesis

“…The O 2 mass transfer and, therefore, the heat released by exothermic reactions is controlled by the size and shape of the channels in honeycomb monoliths [26,27]. In non-adiabatic reactors, radiative heat loss helps to decrease hot spots [28,29]. Lastly, the heat transfer by conduction also plays a role in flattening thermal profiles when using thermally conductive supports [17,22].…”

“…The metals are incorporated by impregnation as their respective salts either before [9,14,29] or after [13,16,23] washcoating the ceramic support, as well as directly on the surface of the structured support [12,15,30]. The impregnation on structured supports may give rise to dishomogeneities in metal dispersion.…”

Reforming Technologies to Improve the Performance of Combustion Systems

“…The CPOX of methane rich mixtures in non-adiabatic monolith reactors was investigated in study by Navalho et al [19]. A rhodium based catalyst was used for the experiments.…”

“…Radiative heat loss can change the heat release as compared to the adiabatic reactor, and make the reaction more exothermic Navalho et al [19] Catalytic Partial…”

Conceptual design of syngas production systems with almost net-zero carbon dioxide emissions

“…The SMR is a catalytic and energy efficient technology for producing a H 2 -rich syngas [1], but the steam reforming is an endothermic reaction in which the operating temperature is usually over 800 K. The POM is another way to produce syngas where non-catalytic partial oxidation of methane occurs only at very high temperatures between 1300 K and 1600 K and catalytic partial oxidation of methane is a relatively inexpensive alternative option but a significant problem is rapid deactivation due to coke formation [2e4]. The DRM is a potential method in production of CO-rich syngas by consuming greenhouse gases such as CH 4 and CO 2 . This process is attractive from the environmental and economic viewpoint because of the potential utilization of greenhouse gases as resources.…”
