DOI: 10.1016/j.cej.2018.08.124
Abstract: Abstract Fixed-bed reactors are widely used for large-scale, heterogeneously-catalyzed gas-phase reactions, such as steam reforming, selective hydrogenations and partial oxidations. These reactions have strong heat effects; exothermic reactions can exhibit “hot-spots”, while endothermic reactions require… read more here.
