Effect of syngas water-to-gas ratio on the shift process
Thread Content
The syngas, saturated with water vapor, produced by the gasifier must pass through a carbon scrubber to remove solid particles before proceeding to the shift process. It is necessary to control the water-gas ratio of the syngas before the shift reaction – what is the purpose of controlling this ratio? What impact does it have on the transformation? I seek advice from those who are more experienced.
You should first figure out what reaction takes place in the converter, then you’ll understand why a water vapor ratio is necessary
Water vapor is a reactant in the shift reaction and is essential; too low a water vapor ratio is unfavorable for the shift reaction
The water vapor ratio is too low, causing the converter to overheat easily； The water vapor ratio is too high, causing the catalyst to easily become powdered!
