Abstract
A catalyst composition contains an inorganic porous material with pore diameters of at least 2 nm and of crystals of molecular sieve. The crystals of molecular sieve have an average diameter, measured by scanning electron microscopy, not bigger than 50 nm. The catalyst composition has a concentration of acid sites ranges from 50 to 1200 μmol/g measured by TPD NH3 adsorption. An XRD pattern of the catalyst composition is the same as an XRD pattern of the inorganic porous material.
