Title:
NOVEL METAL-CONTAINING ZEOLITE BETA FOR NOx REDUCTION
Document Type and Number:
Japanese Patent JP2015205277
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To synthesize an organic-free, metal-containing zeolite beta that enables selective catalytic reduction of NOx in exhaust gas.SOLUTION: There is provided a method of selective catalytic reduction of nitrogen oxides in exhaust gas. The method comprises at least partially contacting the exhaust gas with an article comprising an organic-free, iron-containing zeolite beta having a molar silica-to-alumina ratio (SAR) ranging from 5 to 20. The iron is present in an amount of at least 0.5 wt.%.
