| Abstract: | Pyrazine can be produced via dehydration and dehydrogenation of ethylene glycol and ethylenediamine in the presence of the catalyst. The catalysts was prepared by impregnation in different active components ratios, roasted at differ- ent temperatures, using different carriers of activated carbon, molecular sieve, and δ -alumina, and Cu-Zn-A], Mn-Zn-Cr as the active components. The active components account for 15% of the carrier. The absorbtion of charcoal is the best in those three carriers, so it is the best carrier. Via gas chromatography, it is known that the catalyst which was prepared by soakage of Cu-Zn-A1 nitrate on the activated carbon in the ratio of 1 ： 1 ： 1 by molar, roasted at 350℃, was the most effective and selective. |
