Abstract
A process for initiating and controlling the regeneration of spent fluid catalytic cracking catalyst containing catalytically effective amounts of a C0 conversion promotor and for the essentially complete catalytic conversion of C0 to C02 both in a dense bed of catalyst maintained in an FCC regeneration zone. The process comprises (a) passing to a dense-phase catalyst bed in a regeneration zone said catalyst and fresh regeneration gas at a first flow rate sufficient to oxidize coke to produce partially spent regeneration gas, (b) oxidizing coke at first oxidizing conditions including a catalyst bed first temperature of from 399.degree.C to 677.degree.C to produce regenerated catalyst and partially spent regeneration gas containing C0, (c) increasing the catalyst bed temperature from said first temperature to a second temperature of from 677.degree.C to 760.degree.C, (d) passing to the catalyst bed fresh regeneration gas at a second flow rate stoichiometrically sufficient to essentially completely oxidize C0 to C02, (e) oxidizing in said catalyst bed, maintained at second oxidizing conditions including the presence of said C0 conversion promotor, C0 to produce spent regeneration gas, (f) analyzing spent regeneration gas to obtain a measured free-oxygen concentration and comparing the measured free-oxygen concentration to a predetermined free-oxygen concentration, and (g) thereafter regulating fresh regeneration gas at a third flow rate to maintain the measured free-oxygen concentration equal to the predetermined free-oxygen concentration thereby ensuring essentially complete conversion of C0 to C02. The process is generally distinguishable from the prior art in terms of the C0 conversion temperature employed.
