摘要

提出了一种在多季铵盐的作用下，通过珍珠岩和黑曜石的部分重结晶制备BEA、MOR、MFI、MTW和GIS沸石和纳米复合材料的方法。所制得的材料具有较好的比表面，存在Lewis(高达98 μmol/g)和Bronsted (5 ~ 105 μmol/g)酸位点，在乙醛和乙醇合成1,1-二氧乙烷的过程中表现出催化活性。

Properties of Hierarchy Zeolite Obtained From Obsidian and Perlite

A method for obtaining hierarchical BEA, MOR, MFI, MTW, and GIS zeolites and nanocomposites by partial recrystallization of perlite and obsidian in the presence of polyquaternary ammonium salts, which act as structure-directing agents, is proposed. The obtained materials are characterized by a developed specific surface, the presence of Lewis (up to 98 μmol/g) and Bronsted (5-105 μmol/g) acid sites and show catalytic activity in the process of 1,1-diethoxyethane production from acetaldehyde and ethanol.
