Claims17
A method for synthesizing nanozeolite Y crystals comprising the following steps:
- a) Preparing a first aqueous solution comprising a silicate source and quinuclidine;
- b) Preparing a second aqueous solution comprising an aluminate source and an alkali hydroxide;
- c) Combining the first and the second aqueous solution to obtain an aqueous reaction mixture;
- d) Incubating the aqueous reaction mixture to obtain nanozeolite Y crystals;
- e) Washing the obtained nanozeolite Y crystals with an aqueous washing buffer;
- f) Drying the washed nanozeolite Y crystals to remove residual crystalline water;
- and
- g) Calcining the washed nanozeolite Y crystals.
