ANALYTICAL INVESTIGATION OF THE PERFORMANCE OF CATALYTIC MONOLITHS OF VARYING CHANNEL GEOMETRIES BASED ON MASS TRANSFER CONTROLLING CONDITIONS.

This paper presents a new criterion for comparing the performance of catalytic monoliths of various channel geometries and a better geometry for analyzing channels of wave-like pattern.

Under mass transfer rate controlling conditions, the performance of ducts of different geometry is analyzed and compared on the basis of equivalent duct open area. Results indicate that the monolith length required for a 99% CO conversion is in the following ascending order: conduits of rectangular cross section, wave ducts, equilateral triangles, squares, circles and hexagons.
