ABSTRACT

Zeolite Socony Mobil-5 (ZSM-5) is a synthetic Aluminium silicate zeolite belonging to the pentasil family of zeolite. The vertices are Al or Si and an O is assumed to be bonded between the vertices. In the present work, ZSM-5 was prepared by using Colloidal Silica and sodium aluminate as silicon and aluminium sources respectively. Since ZSM-5 acts as catalyst even at prolonged high temperature, the ZSM-5 is used for the Selective Catalytic Reduction of (SCR) of NOx in the exhaust pipe of diesel engine. A thin ﬁlm of ZSM-5 was developed on the metal sheet by hydrothermal method forms a Selective catalytic reduction (SCR) catalyst of plate type of structure. The characterization of SCR catalyst is carried by subjecting to X-ray diffraction, BET test,erosion test. The surface area per unitv weight for uncalcined sample was 40.635 m²/g. The X-ray diffraction shows that the topology of the prepared silicate-1. The SCR catalytic converter was modeled using COMSOL Multiphysics software. The reactor modeling gave the result of concentration proﬁle of ammonia, NOx gases, velocity proﬁle and pressure proﬁle along the reactor.

Keywords: ZSM-5 catalyst, SCR catalyst, NOx
