In-situ catalytic abatement of NOx during fluidized bed combustion—A literature study

In this study, opportunities, challenges, and possibilities to develop a bed material for in-situ catalytic reduction of NOx during fluidized bed combustion have been identified. Various catalytic materials and processes for abatement of NOx at high temperatures are reviewed, which include De-NOx catalysis, catalytic decomposition, and selective catalytic oxidation of NOx precursors in combustion processes. Possibilities to utilize fly ash from combustion itself for the development are discussed.
