Abstract
Sea water previously filtered and temperature controlled, and which includes added hydrogen is continuously pumped at a constant rate to a deoxygenation reactor containing a divided platinum catalyst on a granular activated carbon support. The deoxygenated sea water is continuously discharged from the reactor through a line. The divided platinum of the catalyst is present in a superficial layer of the support grains and the platinum dispersion in the catalyst grains is at least 10%.
