Abstract

In this work a cobalt-free zeolite-based catalyst formulation is proposed for NOx CH4-SCR towards a commercial application of after-treatment system for heavy-duty vehicles moved by natural gas (lean-gas burn engines). PdCe-HMOR catalyst was characterised by H2-TPR, DRS UV–Vis and TEM/EDS. The effect of [CH4]/[NO] in the gas feed was studied in order to assess the catalytic performance under simulated dynamic engine conditions. The catalyst was also tested with a representative gas feed of real exhaust gases of a heavy-duty vehicle’s engine (lean-burn conditions) powered by natural gas.
