Hydrogen production has started. . Transformation–moderate reduction
Thread Content
According to the information provided, during the initial stage of reduction in the medium-pressure reactor, the inlet temperature must not exceed 250°C. Why is such a requirement?
Is there no steam supply? Just adjust the steam supply and that’s it
After hydrogen addition, the medium-bed layer experiences a temperature rise; the inlet temperature should not be too high
Since the reduction of the catalyst is an exothermic reaction, it is necessary to lower the high-temperature inlet temperature before hydrogenation, in order to enable better control of the bed temperature after hydrogenation
