Microporous Solids

A microporous+mesoporous material composed of MCM-41 and MFI was produced by a two-step synthetic process. The solid, called 99MMM-1,:: was characterized by X-ray di4raction (XRD), N2 physisorption, and transmission electron microscopy (TEM).

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.
