ABSTRACT:
Gaseous hydrogen and oxygen are combined in an upwardly extending casing containing a catalytic assembly in an intermediate portion of the casing with means for distributing hydrogen gas in the catalytic assembly, distributing cooling water and oxygen feeds downwardly from a top portion of the casing on to the catalytic assembly and draining water from a bottom portion of the casing is recirculated. Combined oxygen and hydrogen entrained in the draining water are extracted by tapping water from the recirculating draining water. The catalyst assembly comprises high surface area, porous supports with platinum in the pores and a polytetrafluoroethylene coating over the supports, the platinum particles comprising about 0.1 to about 0.5 weight % of the total weight of the supports, platinum and polytetrafluoroethylene, and the polytetrafluoroethylene comprises about 2 to about 4 weight % of the total weight of support, platinum and polytetrafluoroethylene. Preferably the catalyst assembly has hydrophilic packing interspersed with the porous supports.
