Two FCC catalysts with a 60m average size, prepared with different crystallite sizes (0.4 and 0.9m), are studied in terms of total acidity, energy of ammonia desorption, specific surface area, relative amount of Brönsted and Lewis acid sites, crystallite and particle size, and micropore size distribution.
