Abstract
A zeolite suspension contains MEL-type zeolite nanocrystals as a principal component. A method for the production of MEL-type zeolite nanocrystals includes the steps of aging a synthesized solution comprising TEOS, TBAOH, water and alcohol and subjecting the aged solution to hydrothermal crystallization treatment at a predetermined temperature. A method for the production of a zeolite suspension includes the steps of aging a synthesized solution comprising TEOS, TBAOH, water and alcohol, subjecting the aged solution to hydrothermal crystallization treatment to produce MEL-type zeolite nanocrystals and mixing a composition having a surfactant dissolved in at least one organic solvent or a mixed solvent of alcohol-based organic solvents, amide-based organic solvents and ketone-based organic solvents with a zeolite nano-crystal suspension containing the MEL-type zeolite nanocrystals to produce a zeolite suspension.
