摘　　要：通过对以ＦｅＳＯ４·７Ｈ２Ｏ为原料，以ＮＨ３·Ｈ２Ｏ（或ＮａＯＨ）为沉淀剂共沉淀法制备铁铬系高变催化剂工艺路线的改进，采用新的洗除ＳＯ￣２－＿４方法，使催化剂本体硫显著降低（＜５００ｐｐｍ）。通过正交设计法对工艺条件选优，获得制备低流型Ｆｅ２Ｏ３－Ｃｒ２Ｏ３系高变催化剂的工艺路线。The co-precipitation process for preparation of Fe-Cr high-temperature shift catalyst was improved by adopting new SO￣2-_4scrubbing method. As a result, the sulfur content of the catalyst was considerably reduced. A new process for preparation of low--sulfur Fe-Cr HTS catalyst was obtained on the basis of the optindzation of process condition through orthogonal design.
