Claims18
-3. (canceled)
The method of claim 45, comprising catalytically combusting the fuel mixture at a temperature of below about 140 ° C.
The method of claim 45, wherein the HOC is a noble metal.
The method of claim 45, wherein the ORC is iron, zinc, silver, copper, tin, oxides thereof, or combinations thereof.
-41. (canceled)
The method of claim 45, wherein the heat exchange medium comprises water.
(canceled)
A method for heating a heat exchange medium comprising:
- supplying a fuel and an oxidizer to a catalytic reactor having a catalytic heating element including a catalytic surface having a hydrogen oxidation catalyst (HOC), and a oxygen reduction catalyst (ORC), the catalytic surface adapted to lower the activation energy of a combustion of the fuel mixture such that the combustion occurs at low temperatures;
- catalytically combusting the fuel mixture on the catalytic surface;
- and
- transferring the heat generated by the catalytic combustion to the heat exchange medium.
