Summary

For the first time acetylene was investigated as a reducing agent for the selective catalytic reduction (SCR) of NO in the presence of excess oxygen on metal-exchanged ZSM-5 zeolite catalysts. By using C2H2 as reducing agent, 76% NO conversion to N2 was achieved over In-H-ZSM-5 catalyst under the reaction conditions of 325oC, 1600 ppm NO, 800 ppm C2H2, and 9.95 % O2 in He with GHSV of 17000h-1.
