| Abstract: | A mordenite catalyst modified with Na +,K + was prepared and was used in amination of methanol in gas phase.The results of model test show that the activity of the catalyst and the selectivity of dimethylamine are high.The conversion of methanol is higher than 98% and the selectivity of dimethylamine is higher than 62% at 320～340 ℃ and 1.8～2.0 MPa.Semi-plant test for the preparation of the catalyst and industrial side line test were carried out.The results indicate that the stability and strength of the catalyst are high enough for its use in industry. |
