Abstract:
A method is provided for controlling regeneration of an SCR catalyst. The method includes coordinating the regeneration duration and temperature (e.g., longer/shorter regenerations and/or lower/higher temperatures) to the urea deposit loading. In this way, improved regeneration may be achieved due to the particular nature of urea deposits on SCR catalysts.
