| 简介 |
FIELD : zeolites.
SUBSTANCE : invention relates to aluminosilicate zeolite composition identified as UZM-9, which is characterized by LTA topology and has empiric formula Mm n+Rf p+Al1-xExSiyOz, wherein M represents at least one exchangeable cation selected from group including alkali and alkali-earth metals; R at least two organic cations selected from group including quaternary ammonium salt ions, double quaternary ammonium salt ions, protonated amines, protonated alkanolamines, and quaternized alkanolamine ions; provided that at least one of indicated organic cations contains at least one organic group having at least two carbon atoms; E represents element selected from group including gallium, iron, boron, and mixtures thereof; Si/(Al+E) molar ratio varies from more than 3.5 to 6.
EFFECT : ensured preparation of zeolite resistant to calcination up to 600 degrees and exhibiting catalytic activity in its H-form.
