Abstract
A process for reducing NOx emissions and an FCC process using same as a flue gas cleanup stage are disclosed. Gas containing NOx and entrained catalyst fines is passed up through a bed of catalyst at a sufficient velocity to expand and fluidize the catalyst bed. Particulates deposited on the catalyst are abraided or elutriated away by fluidization, preventing fouling of the DeNOx catalyst. A low pressure drop design, with vertical, perforate gas distributors covered by the bed is also disclosed.
