It is low subtraction of the NOx discharge in FCC processing of sufficient combustion mode

摘要

Catalytic cracking process, the composition in order to decrease the discharge of NOx which occurs desirably during flow catalytic cracking processing is disclosed. As for this composition, the acidic metallic oxide which (i) substantially the zeolite is not included, the (ii) alkaline metal, the alkaline earths metal, and these blends, (iii) oxygen storage metallic oxide, (iv) palladium and the (v) precious metal component, desirably the platinum, iridium, rhodium, osmium, ruthenium, rhenium, and these blends, including, it becomes. It is desirable, this composition is used as the FCC catalyst which circulates and another additive particle which circulates together. The sufficient or the decrease of NOx in the exhaust of the complete combustion FCC reproducing arrangement is achieved, while making the combustion of CO PROMOTE simultaneously.
