用草酸钴生产宽温变换催化剂新工艺

NEW TECHNOLOGY FOR THE PREPARATION OF SULFUR-TOLERANT SHIFT CATALYST HB-4Q BY COBALT OXALATE.

通过试验证实了用草酸钴作钴源，不用氨水作介质，一釜溶解钴钼钾前驱体，一步共浸渍载体γ－Ａｌ２Ｏ３生产球形钴钼宽温变换催化剂新工艺的可行性。使产品ＨＢ－４Ｑ主要性能指标与常规氨络合法产品ＨＢ－１Ｑ处于同等水平。

The test for the preparation of sulfur-tolerant shift catalyst HB-4Q by cobalt oxalate is carried out.It shows that the main performance of this catalyst can reach the level of that of catalyst HB-1Q,which is prepared by conventional ammonia impregnation complex method,and the cost can be lower about RMB 2 000 yuan/m3.
