摘要

Abstract

This work tries to identify the relationship between geometric configuration of monolith catalysts

and transfer and reaction performances for selective catalytic reduction of N

O with CO. Monolith catalysts with five different channel shapes (circle

regular triangle

rectangle

square and hexagon)

was investigated to make a comprehensive comparison of their pressure drop

heat transfer Nu number

mass transfer Sh number and N

O conversion. It was found that monolith catalysts have a much lower pressure drop than that of traditional packed bed

and for monolith catalysts with different channel shapes

pressure drop decreases in the order of regular triangle rectangle square hexagon circle. The order of Nu is in regular triangle rectangle ≈ squarehexagon circle

similar to that of Sh. N

O conversion follows the order of regular triangle rectangular ≈ square ≈ circle hexagon. The results indicate that chemical reaction including internal diffusion is the controlling step in the selective catalytic reduction of N

O removal with CO. In addition

channel size and gas velocity also have influence on N

O conversion and pressure drop.
