Abstract
The operation of a fluid catalytic cracking unit having a regenerator designed to completely combust carbon monoxide to carbon dioxide thermally is improved by circulating a trace amount of at least one metal of the group consisting of platinum, palladium, iridium, osmium, rhodium, ruthenium and rhenium with the circulating inventory of solid acidic cracking catalyst.
