摘要

Abstract

The CuO/γ-Al

/cordierite catalyst

after being sulfated by sulfur dioxide (SO

) at 673 K

exhibits high activities for selective catalytic reduction (SCR) of nitrogen oxide (NO) with ammonia (NH

) at 573-723 K. The intrinsic kinetics of SCR of NO with NH

over CuO/γ-Al

/cordierite catalyst has been measured in a fixed-bed reactor in the absence of internal and external diffusions. The experimental results show that the reaction rate can be quantified by a first-order expression with activation energy

' of 94.01 kJ·mol

and the corresponding pre-exponential factor

when NH

is excessive. However

when NH

is not enough

an Eley-Rideal kinetic model based on experimental data is derived with

. The intrinsic kinetic model obtained was incorporated in a 3D mathematical model of monolithic reactor

and the agreement of the prediction with experimental data indicates that the present kinetic model is adequate for the reactor design and engineering scale-up.
