Title
Plasma-assisted selective catalytic reduction of NOx by C2H2 over Co-HZSM-5 catalyst
Abstract

Investigations on the combination of the dielectric barrier discharge plasma with Co-HZSM-5 catalyst for the selective catalytic reduction (SCR) of NOx by lower hydrocarbons were presented. Compared with the reductant of CH4 and C2H4, C2H2 showed a broader low temperature activity in the SCR of NOx with significant O2 tolerance, as well as enhanced CO2 selectivity under the combination of plasma with the catalyst. With a reactant gas mixture of 500 ppm NOx, 500 ppm C2H2, 15% oxygen in N2 and space velocity of 12 000 h−1. The NOx conversion is higher than 50% in the temperature range of 150–450 °C in this plasma-assisted process. Larger than 90% of NOx conversion was obtained at 300 °C and Ein = 138 J l−1.
