Why does medium-frequency transformation need to be carried out in two stages? Based on the reaction equations and principles, it is known that increasing the temperature helps to accelerate the reaction rate; since the conversion reaction is an exothermic reaction, reducing the temperature can result in a higher conversion rate. To resolve this contradiction, we define two transformations. In the upper conversion section, higher temperatures accelerate the reaction rate, allowing most of the carbon monoxide to be converted there; thereafter, a heat exchanger is used to lower the temperature, so as to achieve a higher conversion rate in the lower conversion section. Therefore, the transformation is carried out in two stages via intermediate variation.

To resolve this contradiction, we define two transformations. The upper-stage conversion accelerates the reaction rate at higher temperatures, with most of the carbon monoxide being converted in the upper part

The purpose of segmentation is, first, to control the hotspot temperature of the bed layer. Secondly, the conversion rate of the shift converter is improved through inter-segment heat exchange or humidification cooling.
Inter-stage heat exchange facilitates temperature control and increases the conversion depth.
First is to control the hotspot temperature of the bed layer. The second method is through inter-segment heat exchange or humidification for cooling
