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

The effect of CaO on emissions of nitric oxide from a fluidised bed combustor

“…solid carbon and CO. Reaction (V) between CO and NO was confirmed above as being catalysed by CaO; the reaction has been observed before [19,20,25,39,50,51], but not studied in any detail. This work has shown that CaO is an even more effective catalyst than Fe 2 O 3 under reducing conditions, for the reduction of NO by CO in (V).…”

“…These three heterogeneous reactions constitute a possible catalytic mechanism, bearing in mind that they add algebraically to give the Boudouard reaction (X). Radicals such as CNO are well known [39] in these environments, but, of course, alternative mechanistic schemes can be devised.…”

Surface science studies of selective catalytic reduction of NO: Progress in the last ten years

“…Such work has been summarized in numerous review papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Fly Ash Utilization for the Development of Low NOx Bed Materials

“…Recently, opportunities and challenges to develop a bed material for in-situ catalytic abatement of NO x in FBC, especially bubbling FBC plants of small and medium sizes, have been identified [1]. Various catalytic materials and processes for abatement of NO x at high temperatures were reviewed, which include De-NO x catalysis with, e.g., CO and C x H y , catalytic decomposition of NO to N 2 , and selective catalytic oxidation of NO x precursors (NH 3 , HCN) in combustion processes.…”
