Title:
安定化したミクロポーラス結晶性材料、その製造方法およびNOxの選択触媒還元のための使用方法
Document Type and Number:
Japanese Patent JP6427610
Kind Code:
B2
Abstract:
There is disclosed a microporous crystalline material having pore opening ranging from 3 to 5 Angstroms, where the material comprises a first metal chosen from alkali earth group, rare earth group, alkali group, or mixtures thereof, and a second metal chosen from iron, copper or mixtures thereof; and has a molar silica to alumina ratio (SAR) from 3 to 10. The microporous crystalline material disclosed herein may comprise a crystal structure having building units of double-6-rings (d6r) and pore opening of 8-rings as exemplified with framework types defined by the Structure Commission of the International Zeolite Association having structural codes of CHA, LEV, AEI, AFT, AFX, EAB, ERI, KFI, SAT, TSC, and SAV. There is also disclosed a method of selective catalytic reduction of nitrogen oxides in exhaust gas, comprising at least partially contacting the exhaust gases with an article comprising the disclosed microporous crystalline material.
