FCC catalysts

A new method for the synthesis of nanosized zeolites in organic solvents, such as formamide and toluene as crystallization medium instead of water, in the presence of organosilane has been developed. Organic solvents have a great impact on the synthesis of nanozeolites.

Two FCC catalysts with a 60
m average size, prepared with different crystallite sizes (0.4 and 0.9
m), 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.
