Additives for diminishing the content of carbon monoxide in gases formed in regeneration of the cracking catalyst without noble metals were synthesized and tested. As additives of this kind can serve mixed oxides based on copper, cerium, magnesium, and aluminum and manganese oxide supported by gamma aluminum oxide. Additives based on mixed oxides possess a high acidity and do not impair the activity of the catalytic system in the cracking reactions. In the efficiency (89.7–95.5%) in lowering the content of carbon monoxide, mixed oxides based on copper and cerium are comparable with the platinum-based additive KO-10 (96.8%). The activity of the additive based on manganese oxide depends on the sample calcination temperature, with the maximum efficiency in lowering the content of carbon monoxide (88.0%) reached at temperatures of 850–920°C.
