Investigation of ethylene glycol reforming as a source of reductants for catalytic NOx removal from diesel exhaust
Ethylene glycol (EG) reforming was investigated as a method to generate H-2 and CO reductants for low-temperature lean NOx reduction. Stable production of H-2 was obtained at 230 degrees C over a Pt/Al2O3 catalyst using a feed consisting of 2-5% O-2 and > 2.2% EG. The presence of H2O in the feed enhanced H-2 production, as did Na modification of the catalyst. Water gas shift was determined not to contribute significantly to H-2 production during EG reforming.
