Abstract
The dual template synthesis of zeolite SSZ-13 by use of trimethyl-adamantanammonium hydroxide and a diquaternary-ammonium mesoporogen induces considerable mesoporosity without impeding zeolite microporosity. The strongly improved accessibility of Brønsted sites in mesoporous SSZ-13 increases its stability during application as an acid catalyst in the methanol-to-olefins reaction.
摘要
采用三甲基-金刚烷氢氧化铵和双季铵盐介孔导向剂双模板合成 SSZ-13 沸石，在不阻碍沸石微孔的情况下引入了可观的介孔。介孔 SSZ-13 中 Brønsted 位的可及性大大提高，使其在作为甲醇制烯烃反应中的酸性催化剂应用时的稳定性增强。
