The present invention relates to new crystalline zeolite SSZ-52x prepared using a quaternary ammonium cation templating agent, for example, having the structure: wherein X- is an anion which is not detrimental to the formation of the SSZ-52x. SSZ-52x is useful as a catalyst and shows improved durability, particularly with regard to NOϰ conversion.
本发明涉及使用季
铵盐模板剂制备的新型晶体
沸石SSZ-52x,例如具有以下结构的模板剂:其中X-是对SSZ-52x的形成没有不利影响的阴离子。SSZ-52x可用作催化剂,并显示出改进的耐久性,特别是在NOx转化方面。
