摘　　要：我国已有29套大型制氨装置投入运行，近四年来累计更换催化剂5860．74t。单耗为2．383t／104tNH3，比前5年的3.47t／104tNH3有大幅度下降。随着新型催化剂的开发，催化剂国产化率有了明显的提高．但大型氨厂近年来在催化剂的使用中也存在一些问题，这使得单耗与国外先进水平相比仍有一定差距，也表明我国的大型氨厂在催化剂性能和使用技术方面仍有待进一步提高。There are now 29 large-scale ammonia plants in operation in China, with a catalyst changeover of 5860. 74 tons and specific consumption of 2. 383 t/104 t NH3 in last four years, a considerable reduction compared with 3. 47t/104tNH3 in the five years before this period. With development of new .catalysts,percentage of domestic catalysts in use has a considerable increase. However, there are still some problems in the use of catalysts in large-scale ammonia plants which make the specific consumption of catalysts still higher than the advanced level abroad. Therefore, there is still much to do to improve performance and application technique of the catalysts in domestic large-scale ammonia plants.
