Steam/Carbon mole ratio in steam methane reforming

01 January 1970 1 1K Report

Why steam to carbon ratio is increased with decreasing the feed flow rate at the reformer inlet?

Also why Steam/CO ratio is increased at inlet of isothermal (MT) shift reactor inlet at turn-down condition? -

Decreasing in the flow rate will increase the residence time which may favor the formation of more by-products. The catalyst and its selectivity will also play an important role.
