摘要
本文详细地介绍了小氮肥变换工段从单纯的中温变换流程、中—低温变换流程，到中串低变换流程，再到全低变流程，中—低—低变换流程的沿革历史，着重指出变换工艺流程的沿革始终以各种新型的中、低温变换催化剂的成功开发为中心。另外，还简述了适合于各种工艺流程的变换催化剂，并指出了各变换流程运作中所存在的问题。最后，作者提出了自己的建议与看法。
With all kinds of shift catalysts developing success fully,there are the evolution of shift technological process in mini-type nitrogenous fertilizer plant.In article,activator kinds of shift process are introduced in detail,furthermore,relevant catalysts also described.In addition,the problems among all kinds of shift conversion process are pointed out and pieces of advice are given at last.
