Multiplicity Regions in a Moving‐Bed Reactor: Bifurcation Analysis, Model Extension, and Application for the High‐Temperature Pyrolysis of Methane

Abstract: This paper reports studies on the bifurcation analysis and the generation of regions of multiplicity in the operation of moving-bed reactors. The studies were first carried out for a generalized model, which allows the investigation of the effect of various scenarios, such as changes in heat capacity or the number of moles with reaction, as well as the previously unstudied equilibrium and allothermic reactions. The insights gained from this extension were then applied to an actual reaction, namely the high tem… Show more

“…Already in 1961 Jahnig et al published a patent for an electrically heated moving bed reactor 8. Munera‐Parra et al then showed theoretically that countercurrent operation is an efficient method of heat input 9. The carbon deposits appear at the hottest points in the reactor, so that in the fluidized bed and in the moving bed the carbon deposits are most likely to occur at the walls or electrodes where they would inhibit further energy input and cause clogging of the reactor.…”

“…A promising reactor concept for the TDM without a catalyst is the heat integrated moving bed reactor [7,25], which enables a continuous withdrawal of the carbon produced from the reactor and an efficient heat integration. Reported reaction temperatures are up to 1500 K at a residence time up to 10 s [23].…”
