Abstract
High-temperature catalytic processes such as partial oxidation

of Methane (POX) and steam Methane reforming (SMR)

may benefit from use of reactor systems using monolithic honeycomb

structures. Hereby, process performance is enhanced

through more efficient heat transfer and considerable smaller reactor

foot-prints than for conventional reactor concepts. Compact

ceramic heat exchange structures may also be an interesting

option for increasing the energy efficiency of high temperature

processes in general. One example is single cycle turbines where

these structures can be used as recuperators. The purpose of

this paper is to describe modelling of gas... (More)
High-temperature catalytic processes such as partial oxidation

of Methane (POX) and steam Methane reforming (SMR)

may benefit from use of reactor systems using monolithic honeycomb

structures. Hereby, process performance is enhanced

through more efficient heat transfer and considerable smaller reactor

foot-prints than for conventional reactor concepts. Compact

ceramic heat exchange structures may also be an interesting

option for increasing the energy efficiency of high temperature

processes in general. One example is single cycle turbines where

these structures can be used as recuperators. The purpose of

this paper is to describe modelling of gas flow pattern and heat

transfer in reactors and heat exchangers with monolithic based

structures. This technology is currently under development in a

partnership of European companies and academia, with financial

support from the EC and Swiss Government. The mathematical

model developed for heat transfer and flow maldistribution

has been used for counter-current checkerboard channelarrangement.

Pressure drop has been analyzed both experimentally

and numerically (computation fluid dynamics, CFD). Power

density has been shown to depend on various reactor parameters.

Channel geometry, inlet gas temperature difference and

channel wall thickness have been calculated to find the influence

on power density. (Less)
