REMOVAL OF HYDROGEN IMPURITY FROM GAS STREAMS

Trace hydrogen may be removed from a dry gas by passing the dry gas at a temperature from about 0°C to about 60°C through at least one layer of a first hopcalite catalyst to produce product gas that is at least substantially free of hydrogen, wherein the first hopcalite catalyst has a molar ratio of...

More Information
Summary:Trace hydrogen may be removed from a dry gas by passing the dry gas at a temperature from about 0°C to about 60°C through at least one layer of a first hopcalite catalyst to produce product gas that is at least substantially free of hydrogen, wherein the first hopcalite catalyst has a molar ratio of copper to manganese of more than 0.55. Advantages include increase hydrogen capacity, lower feed and regeneration temperatures and lower sensitivity to carbon dioxide than equivalent processes using standard hopcalite catalyst having a Cu/Mn molar ratio from 0.45 to 0.55.
