ABSTRACT:
A fluidized-bed process for catalytic cracking of a hydrocarbon feedstock where the hydrocarbon feedstock, particularly a feedstock with a high content of basic nitrogen compounds, and a catalyst circulate in the tubular zone co-currently from the top to the bottom, where the catalyst, which is under equilibrium conditions at 150.degree. C., and a pressure of 5 mbar, adsorbs less than 250 micromols, and preferably less than 50 micromols, of pyridine/g, and whose pyridine retention, after heating at 350.degree. C. under vacuum, does not exceed 20%, and preferably not 10%, of the amount adsorbed at 150.degree. C.
