METHOD FOR SYNTHESIZING MESOPOROUS NANO-SIZED ULTRA-STABLE Y ZEOLITE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18059728 titled 'METHOD FOR SYNTHESIZING MESOPOROUS NANO-SIZED ULTRA-STABLE Y ZEOLITE

Simplified Explanation

The abstract describes a method for synthesizing a mesoporous nano-sized ultra-stable Y zeolite.

• Adding sodium aluminate and colloidal silica to an aqueous NaOH solution and mixing to form a hydrogel with specific molar ratios.
• Heating the hydrogel to form a zeolite precursor, which is then filtered and washed to obtain a nano-sized Y zeolite.
• Combining the nano-sized Y zeolite with water to form a slurry, then adding an aqueous solution of ammonium hexafluorosilicate to create a dealuminated solution.
• Filtering and washing the dealuminated solution to form an ultra-stable Y zeolite precursor, which is dried and calcined to produce the nano-sized ultra-stable Y zeolite.

Original Abstract Submitted

Methods for synthesizing a mesoporous nano-sized ultra-stable Y zeolite include adding sodium aluminate and colloidal silica to an aqueous NaOH solution and mixing to form a hydrogel having a molar ratio composition of 8 to 12 NaO:AlO:14 SiO:200 to 400 HO. The method further includes heating the hydrogel to an autoclave to form a zeolite precursor which is filtered and washed to form a nano-sized Y zeolite. Further the method includes combining the nano-sized Y zeolite with water to form a nano-sized Y zeolite slurry mixture and then adding a 0.1 to 2.0 M aqueous solution of ammonium hexafluorosilicate to form a dealuminated solution. Finally the method includes filtering and washing the dealuminated solution with water to form an ultra-stable Y zeolite precursor, drying the ultra-stable Y zeolite precursor, and calcining the dried zeolite precursor to form the nano-sized ultra-stable Y zeolite.
