Reduction of gas phase reduced nitrogen species in partial burn FCC processes |
| abstract |
Reduced emissions of gas phase reduced nitrogen species in the off gas of an FCC regenerator operated in a partial or incomplete mode of combustion is achieved by contacting the off gas with an oxidative catalyst/additive composition having the ability to reduce gas phase nitrogen species to molecular nitrogen and to oxidize CO under catalytic cracking conditions. The oxidative catalyst/additive composition is used in an amount less than the amount necessary to prevent afterburn. Fluidizable particles of the oxidative catalyst/additives are circulated throughout the partial or incomplete burn FCC unit along with the FCC catalyst inventory. The flue gas having a reduced content of gas phase reduced nitrogen species and NO x is passed to a downstream CO boiler, preferably a low NO x CO boiler. In the CO boiler, as CO is oxidized to CO 2 , a reduced amount of gas phase reduced nitrogen species is oxidized to NO x , thereby providing an increase in the overall reduction of NO x emitted into the environment. |
