Abstract:
Steaming of NH4Y zeolite at 723 K and 873 K is accompanied by the formation of extra-framework amorphous aluminosilicate and silica gel in addition to earlier observed extra-framework aluminum species. Their occurrence is directly associated with the formation of mesopores. Bulk (intracrystalline) mesopores occur inside the crystallite nuclei and surface (intercrystalline) mesopores are located nearby the crystallite surface. Corrosion of the zeolite framework results in a loss of crystallinity and, consequently, decreased catalytic activity of the USY catalysts synthesized. Analysis of the reasons of mesopore formation may help to reduce these disadvantages.
