Abstract:
An incipient wetness impregnation method for preparing a tin-containing zeolitic material having framework type BEA, a novel tin-containing zeolitic material having framework type BEA and its use.
Abstract:
A process for preparing a tin-containing zeolitic material having framework type BEA, comprising providing an aqueous synthesis mixture comprising a boron source, a silicon source, and a BEA structure directing agent; subjecting the synthesis mixture provided in to hydrothermal pre-crystallization conditions; adding the tin source to the obtained mixture; subjecting the obtained aqueous synthesis mixture to hydrothermal crystallization conditions, obtaining a tin-containing zeolitic material having framework type BEA comprised in its mother liquor.
Abstract:
A process for preparing a tin-containing zeolitic material having a BEA framework structure comprising providing a zeolitic material having a BEA framework structure having vacant tetrahedral framework sites, providing a tin-ion source in solid form, incorporating tin into the zeolitic material via solid-state ion exchange, calcining the zeolitic material, and treating the calcined zeolitic material with an aqueous solution having a pH of at most 5.
