【Q&A No. 031】January 31, 2018: What is medium-temperature shift? Using Fe2O3 as the main catalyst, the operating temperature range is 350–550°C. Due to these temperature constraints, about 3% of the carbon monoxide remains in the gas after the shift process. This type of CO conversion at high temperatures is referred to as medium-temperature shift. (Unless otherwise specified, all Q&A questions are based on hydrogenation units.) ) Due to the limits on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

What is medium-temperature shift? Answer: It uses Fe2O3 as the main catalyst and operates at temperatures ranging from 350 to 550°C. Due to the limitations imposed by these operating temperatures, about 3% of carbon monoxide remains in the gas after the shift process. This type of CO conversion at high temperatures is known as medium-temperature shift.
Using iron oxide trioxide as a catalyst, at a temperature of 210–330 degrees, the gas shift reaction is carried out with 2–4% CO present.
Using Fe2O3 as the main catalyst and an operating temperature range of 350–550°C, about 3% of carbon monoxide remains in the gas after conversion due to the limitations imposed by the operating temperature. This process of CO conversion at high temperatures is known as medium-temperature conversion
Using iron oxide trioxide as a catalyst and an operating temperature range of 350–550, 3% of CO remains after the gas reaction due to limitations in the operating conditions; this process of converting carbon monoxide at high temperatures is known as medium-temperature shift
Catalysts based on iron oxide are used at temperature ranges of 350°C–550°C; the gas resulting from the conversion process still contains 2–4% CO, and this type of conversion is referred to as high- and medium-temperature conversion.
Using Fe2O3 as the main catalyst and an operating temperature range of 350–550°C, about 3% of carbon monoxide remains in the gas after conversion due to limitations imposed by the operating temperature. This CO conversion process at high temperatures is known as medium-temperature conversion.
At a certain temperature (350–390°C), carbon monoxide reacts with water vapor to produce carbon dioxide and hydrogen; this reaction is known as the medium-temperature shift reaction.
