Reaction Conditions

Reaction Steps

A CuCHA powder catalyst was prepared by ion-exchange with copper acetate. A 0.40 M of copper (II) acetate monohydrate solution was prepared by dissolving 89.8 g of the copper salt in 1.125 L of deionized water at 70° C. 300 g of NH4+-form CHA was then added to this solution. An ion-exchange reaction between the NH4+-form CHA and the copper ions was carried out by agitating the slurry at 70° C. for 1 hour. The pH was between 4.8 and 4.5 during the reaction. The resulting mixture was then filtered, washed until the filtrate had a conductivity of <200 μScm−1, which indicated that substantially no soluble or free copper remained in the sample, and the washed sample was dried at 90° C. The obtained CuCHA catalyst comprised CuO at 3.06% by weight and Na2O at 140 ppm.
