This paper synthesizes ZSM-5 zeolite from coal fly ash and uses it as a catalyst for reduction
of NOx emissions in gasoline powered engine. It suggests a mono and bimetallic doped …

The present investigation deals with the synthesis of ZSM-5 zeolite from coal fly ash and
using it as a catalytic convertor for the reduction of NOx in gasoline powered engine. Copper …

NOx reduction from gas stream by selective non-catalytic reduction (SNCR) using urea as a
reducing agent was performed in this study. A Pilot-scale experimental system was …
