Claim 6:
7. A method for synthesizing a microporous aluminotitanosilicate crystalline zeolite according to claim 1, the method comprising at least the following steps:
(i) preparing a mixture comprising at least water and
an aluminum source,
an alkali source,
a structure directing agent,
a silicon source,
a crystalline aluminosilicate zeolite having a three-dimensional framework of AlO2 and SiO2 tetrahedral units and having an MSE framework type,
(ii) heating the reaction mixture at a temperature from 100° C. to 200° C., for a time sufficient to form a zeolite,
(iii) dealuminating of the zeolite with an acid,
(iv) optionally calcining the dealuminated zeolite at a temperature from 500 to 1000° C.,
(v) contacting the zeolite with a titanium source; and
(vi) calcining the zeolite at a temperature from 500 to 1000° C.
