Additives have been synthesized and tested to reduce the content of CO and NOx oxides in the gases of regeneration of FCC without the use of noble metals. The following can be used as additives to reduce CO: mixed oxides based on copper, cerium, magnesium and aluminum. According to the efficiency (89.7-95.5%) of the reduction in the CO content, mixed oxides based on copper and cerium are comparable with the additive based on platinum KO-10 (96.8%). All additives to reduce CO lead to an increase in the formation of NOx oxides. Additives based on mixed oxides (47.0%) are less conducive to this compared to platinum based additives (71.0%). Zeolite ZSM-5 modified with copper and iron can be used as an additive with the function of joint reduction of CO and NOx oxides. The effectiveness of reducing CO is close to 100%, and for NOx oxides it is 45.9%. [ABSTRACT FROM AUTHOR] |
