摘　　要：本文对以铁和硝酸为主要原料制备大型合成氨厂铁基无硫无铬型 CO高温变换催化剂的干燥方式进行了研究 ,探讨了喷雾干燥机的进口温度、固液比等对物料含水量的影响 ,并对普通箱式干燥和喷雾干燥方式对催化剂性能的影响进行了研究 .The drying mode of iron based non sulfure and non chromium catalyst for high temperature CO shift reaction has been studied.This drying mode is usually applied in large synthetic ammonia industrial enterprises that use iron and nitric acid as major raw materials for catalyst preparation.The effect of inlet temperature of the spray drier,the solid liquid ratio and others on water content of raw materials has been investigated.In addition,a comparison has been drawn between the effects of box drying and spray drying on catalytic activity.
