Abstract
A process of removing ammonia from an ammonia-containing gas mixture including introducing a precursor of nitrogen oxides into the gas mixture at a temperature above the decomposition temperature of the precursor and subsequently contacting the gas steam with a catalyst composition which catalyses the reduction of nitrogen oxides in the presence of ammonia to obtain a gas mixture having a reduced ammonia content.
