| Abstract: | As one of the key steps in syngas to ethylene glycol,synthesis of dimethyloxalate(DMO) from CO and methyl nitrite has attracted much attention.Recent progress in deactivation and reuse of Pd/α-Al2O3catalyst for DMO synthesis was reviewed.Problems existing in the reutilization process of Pd/α-Al2O3 catalyst were analyzed,and future development direction was discussed.It was pointed out that research on deactivation of Pd/α-Al2O3 catalyst should based on problems in industrial application to develop target regeneration process.Extraction and adsorption process of Pd/α-Al2O3 catalyst recovery gradually became focus of this area.Development of high efficiency,low cost and green process was reutilization direction of deactivated Pd/α-Al2O3 catalyst. |
