Abstract
A commercial styrenic polymer (Amberlite® XAD4) was hyper-cross-linked (XAD4-HC) using 1,2-dichloroethane to increase micropore volume and NO oxidation performance. XAD4-HC showed 100% higher NO conversion under dry conditions compared to XAD4 when 1 g catalyst was used. A maximum of 68% NO conversion was obtained for XAD4-HC by increasing catalyst mass to 2.5 g. Additionally, the hyper-cross-linked polymer successfully oxidized NO in the presence of 50% RH with minimal (< 9%) performance reduction. This is notable because moisture in the flue gas inhibits NO oxidation for traditional porous catalysts, such as AC and zeolites. Therefore, this work proves for the first time that cost-effective NOx emissions control via liquid absorption is more practical when using hydrophobic microporous polymers as NO oxidation catalysts.
