Abstract

A process for regenerating a coked catalytic cracking catalyst which the carbon-containing deposits on the catalyst contains at least 1 wt % bio-carbon, based on the total weight of carbon present in the carbon-containing deposits is provided. Such coked catalytic cracking catalyst is contacted with an oxygen containing gas at a temperature of equal to or more than 550° C. in a regenerator to produce a regenerated catalytic cracking catalyst, heat and carbon dioxide.
