A method and exhaust gas treatment system for treating an ammonia-containing exhaust gas, for example a livestock house exhaust gas. The exhaust gas treatment system comprises a plurality of sorbent beds comprising a copper-doped small-pore zeolite, a valve system configured to establish independently for each sorbent bed fluid communication in a first or second configuration, wherein in the first configuration a flow of ammonia-containing exhaust gas contacts the sorbent bed at a temperature of less than 50° C. for storing the ammonia; and in the second configuration a flow of heated gas maintains the sorbent bed at a temperature of at least 300° C. for releasing and treating the ammonia in situ.
