Modified zeolites that include amine functionalities and methods for making such

A method of processing a hydrocarbon feedstock, the method comprising contacting the hydrocarbon feedstock with a modified zeolite to form a product, wherein the modified zeolite comprises:

• a microporous framework comprising a plurality of micropores having diameters of less than or equal to 2 nm, wherein the microporous framework comprises at least silicon atoms and oxygen atoms;
• a plurality of mesopores having diameters of greater than 2 nm and less than or equal to 50 nm, wherein the plurality of mesopores are ordered with cubic symmetry;
• and
• wherein the microporous framework is a silica framework, an aluminosilicate framework, or a titanosilicate framework;
• wherein the modified zeolite comprises:
• isolated terminal primary amine functionalities bonded to silicon atoms of the microporous framework;
• or
• silazane functionalities wherein the nitrogen atom of the silazane bridges two silicon atoms of the microporous framework;
• or
• both;
• and
• wherein the modified zeolite is an FAU framework type zeolite.

A method of making a modified zeolite, the method comprising:
