Abstract:
The present invention relates to a method for preparing MWW type zeolite; said method comprising i) intimately mixing together, in the absence of any organic structure directing agent or crystalline MWW type zeolite seeds, a predetermined quantity of a source of silicon dioxide, a source of metal oxide, water and a pH modifier to obtain an aqueous amorphous metallosilicate gel; and ii) hydrothermally treating said gel in the presence of an organic templating agent to provide a crystalline MWW type zeolite.
