PRODUCING HYDROGEN BY CATALYTIC SHIFT REACTION

摘要

Catalytic shift is effected in a reactor provided using a copper catalyst in indirect heat exchange with boiling water at a gas flow rate of 200 to 800 kg mol per hour per m<3> of catalyst. The shift is effected using an outlet temperature in the range 230 to 280 DEG C that is preferably 10 to 30 DEG C below the maximum, or inlet, temperature. The heat exchange surface is 30 to 200 m<2> per m<3> of catalyst.
