Major effect—Catalyst bed input gas temperatures

Catalyst bed input gas temperatures are readily adjusted by heating and cooling the gas in boilers, economizers, heat exchangers etc. Industrial input temperatures vary from 

8 and 18.9 show how catalyst bed input gas temperature affects intercept SO2 oxidation efficiency. Efficiency increases significantly with decreasing input gas 

This result suggests that industrial catalyst bed input gases should always be as cool as possible - consistent with steady, well controlled, long term catalyst bed operation.
