| Abstract: | The microcalorimetric technique is employed to study the interaction of NO and NO 2 with the In/HZSM 5 catalyst which has been reported to be active for the selective catalytic reduction (SCR) of NO by CH 4. The amounts of chemisorption and differential heat of NO 2 adsorption on In 2O 3, HZSM 5 and In/HZSM 5 are much larger than those of NO. Furthermore, NO 2 adsorption on In 2O 3 is irreversible. Associating with the results of in situ IR and TPD, and the NO x conversion in NO(NO 2)+CH 4 system over In/HZSM 5 and HZSM 5 catalysts, it is reasonable to propose that in the CH 4 SCR process NO 2 plays a key role, and NO 2 species chemisorbed on the HZSM 5 support can migrate to the In sites to react with CH 4. |
