Abstract

The reactivity of a Mn‐substituted hexaaluminate catalyst in the catalytic combustion of gasified biomasses‐derived fuels is addressed. The combustion activity of the main fuel components, i.e., CO, H2, C2H4 and CH4, is investigated, along with that of NH3 that is present in the biomasses‐derived fuels. It is found that significant amounts of NOx are formed from ammonia during the catalytic combustion process, but the occurrence of gas‐phase homogeneous reactions involving NH3 and NO in the presence of oxygen strongly reduce NOx formation at high temperatures.
