A new reactor concept for endothermic high-temperature reactions

Flow Distribution Concepts for New Type Monolithic Co- or Countercurrent Reactors

“…5). The ceramic monolith has a square cross section of 152 152 mm 2 combustion gases is reversed in the head of the reactor and the gases leave the monolith downward through the bottom front side of the monolith.…”

“…Again a palladium catalyst was used. In order to prevent the condensation of the water vapor, the heads were thermostatted to 120 C. First experimental results are reported in [2].…”

“…Here, a wall reactor concept [7,8] was utilized and developed further. The steam reforming of methane served as an example [2].…”

Simulation of a Compact Multichannel Membrane Reactor for the Production of Pure Hydrogen via Steam Methane Reforming

“…The model was isothermal, unlikely for a countercurrent configuration, and they operated at 1160 K, well beyond the usual safe operating temperature range of 773-923 K for Pd-based membranes. While modeling of MCMRs for H 2 production via SMR is limited, there have been several attempts to model the MCR [15][16][17][18][19][20][21]. Plate heat exchangers often operate in a countercurrent mode for optimal heat transfer [15].…”

Modeling of a compact plate-fin reformer for methanol steam reforming in fuel cell systems

“…The feasibility of combining in an autothermal micro-channel reactor for methanol reforming with total oxidation of methanol as the heat source has been demonstrated by Reuse et al [20]. The coupling of methane steam reforming with catalytic combustion in adjacent channels has also been studied by Zanfir and Gavriilidis [18] and Frauhammer et al [21]. In the present work, a highly favorable design for efficient coupling of an endothermic steam reforming reaction with a heat source has been proposed, and the main feature is the adopting of a compact plate-fin reformer (PFR) derived from a plate-fin heat exchanger.…”
