✦ Synopsis

An analysis of chemical reactors according to their use of internal and external heat and mass transfer reveals a new reactor configuration -a chromatographic reactor with periodically reversing flow_ The application of this configuration in the removal of nitrogen oxides from stack gases by selective catalytic reduction with ammonia is described_ The new reactor offers high NOx-removal rates without ammonia slip emissions and ameliorates problems associated with the fluctuations and distribution of the gas. The detailed kinetic modelling and preliminary experiments used to establish the feasibility of the process are presented. The necessary criteria for the use of this new reactor type and its relationship to the catalytic heat regeneratorreactor are discussed.
