Reaction Conditions

Reaction Steps

A Cu containing catalyst was prepared by ion-exchange with copper acetate. A 0.3 M copper (II) acetate monohydrate solution was prepared by dissolving 96 g of the copper salt in 1.6 L of deionized water at 60° C. 300 g of the calcined zeolite of example 1 was then added to this solution. An ion-exchange reaction between the H-form of the calcined zeolite described in example 1 and the copper ions was carried out by agitating the slurry at 60° C. for 1 hour. The pH was between 4.5 and 4.8 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 Cu catalyst comprised CuO at 3.29% by weight and Na at 300 ppm, both reported on a volatile free basis. The BET surface of the calcined material was 468 m2/g, determined according to DIN 66131, and the Langmuir surface area was 636 m2/g, determined according to DIN 66135.
