Özet
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 zeolite coated in honeycomb structure cordierite monolith for effectively reducing the NOx emissions. The synthesized ZSM-5 zeolite was subjected to SEM, XRF and XRD analysis and compared with commercial ZSM-5 zeolite. The experimental study of measuring emissions using AVL DI-gas analyzer on a Tata nano twin-cylinder spark ignition engine clearly indicated that inhouse made bimetallic of Ce.Cu-ZSM5 and Ce.Fe-ZSM5 were able to reduce the NOx by 69 % and 75 % at 16 kW. The NOx reductions were much better than those of the commercial catalytic converters.
