Abstract:
1. A process for forming a calcined mesoporous aluminosilicate composition which comprises: (a) providing protozeolitic aluminosilicate seeds selected from the group consisting of an aqueous solution, gel, suspension wetted powder and mixtures thereof, wherein the protozeolite seeds are formed using a structure director selected from the group consisting of organic onium ions, alkali metal ions and mixtures thereof; (b) reacting in a mixture the seeds in an aqueous medium with an organic surfactant selected from the group consisting an alkyl quaternary ammonium surfactant with a hydrophobic segment which contains between 8 to 36 carbon atoms, a non-ionic surfactant containing a polyethylene oxide block as a hydrophilic segment, and a non-ionic amine surfactant; (c) aging the mixture of step (b) at a temperature between 25° and 200° C. to obtain a precipitate of the composition; (d) separating the composition from the mixture of step (c); and (e) calcining the composition of step (d) to form the calcined mesoporous composition, wherein the calcined mesoporous composition does not exhibit x-ray reflections characteristics of an atomically ordered zeolite.
