Hydrogen is removed from CO2 raw gas (containing CO) which is used for synthetic urea, which belongs to an H2-O2 catalytic reaction under special conditions. For safty it have to removing H2 from CO2 in front of Urea units . Our catalyst is widly used in our urea plant .
DZC-P50-is used to promote the catalytic conversion of hydrogen in the CO2 stream upstream of Urea synthesis reactors with excess oxygen added.
Hydrogen is a safety risk and needs to be removed from levels of several thousand ppm by volume to below 10 ppm by volume. Alternative uses are the conversion of oxygen with hydrogen or carbon monoxide or the conversion of hydrogen with oxygen to quantitatively remove these impurities in the respective gas streams.
