Why is deep reduction required for methanation catalysts? What temperature control is needed for deep restoration? The methanation catalyst begins to undergo reduction reactions at around 300°C, but the degree of reduction is low, less than 10%. When the temperature is raised to 355°C, the degree of reduction is generally around 70%; only when the temperature reaches about 400°C does the reduction occur more thoroughly. So a deep restoration is required. During catalytic deep reduction, it is appropriate to control the temperature at 400–430°C. Do not exceed 450°C.
Catalyst deep reduction is carried out to restore its catalytic activity, with the temperature controlled at 400-450℃

Methanation catalysts begin to undergo reduction reactions at around 300°C, but the degree of reduction is low, at about 10%. When the temperature rises to 355°C, the degree of reduction is generally around 70%; only when the temperature is increased to around 400°C does the reduction occur more thoroughly. So a deep restoration is required. During catalytic deep reduction, the temperature should be maintained between 400 and 430°C; it should not exceed 450°C℃
