介绍了绝热变换、等温变换的技术特点，并以某煤制油项目（间接液化）为例，分别从工艺流程、系列数、主要设备、催化剂及公用工程消耗等方面对2种变换技术方案进行了论述；从流程配置、技术经济等方面进行了2种变换技术的比较和分析。结果表明，绝热变换技术和等温变换技术在煤制油（间接液化）项目中的技术经济性总体差别不大。

The characteristics of adiabatic CO shift and isothermal CO shift technologies are introduced.Based on a certain coal to liquid (indirect liquefaction) project,these two CO shift technologies are reviewed from aspects of process flow,trains number,key equipment,catalyst and utilities consumption,and are compared and analyzed from process configuration and technical economics.The results show that the economics has no obvious difference between the adiabatic CO shift technology and the isothermal CO shift technology for coal to liquid project (indirect liquefaction).
