Improving the Si/Al ratio of zeolite omega by boron adulteration

Abstract Boron substituted omega (MAZ) was directly synthesized and the synthesis conditions were systemically investigated, focusing on reducing the template usage by employing ageing and seeding processes. Boron substituted zeolite omega was characterized by 11 B, 27 Al, 29 Si and 2D 31 Al 3Q MAS NMR to study the structure and dealuminization process. The result suggested that boron adulteration is a good way to improve the Si/Al ratio of omega.
