Abstract
The invention relates to a mesoporous zeolitic material having a stereoregular arrangement of uniformly-sized mesopores with diameters ranging from 20 to 500 Å and walls having a microporous nanocrystalline structure. The mesopore walls have a stereoregular arrangement of uniformly-sized micropores with diameters less than 15 Å. The mesoporous zeolite material according to the invention displays both the catalytic properties associated with zeolites containing strong Brönsted acid sites and the large mesopore surface area associated with mesoporous molecular sieves.
