Abstract
A method for crystallizing aluminosilicate zeolites, including the steps of preparing a mixture containing a silica source, a mineralizing agent, an organic structure directing agent; heating the mixture to form a heated mixture; and adding an alumina source to the heated mixture. The method steps described herein can provide an accelerated aluminosilicate zeolite crystallization process as compared to conventional processes.
Claims30
A method of crystallizing zeolites, comprising:
- preparing a mixture comprising a silica source, a mineralizing agent, an organic structure directing agent, and zeolite crystals;
- heating the mixture to form a heated mixture;
- and
- adding an alumina source to the heated mixture,
- wherein the heated mixture comprises about 75 wt. % or less of alumina source in the heated mixture prior to the adding step, based on a total amount of alumina source employed in the method.
