ABSTRACT:
The invention provides a method of preheating a catalyst in a catalytic heater comprising the steps of preparing a gaseous mixture of hydrogen and nitrogen in a volume ratio of between about 95% hydrogen to about 5% nitrogen and about 5% hydrogen to about 95% nitrogen and dispersing the gaseous mixture into contact with the catalyst for a period of time sufficient to raise the temperature of the catalyst to a level that will promote the flameless oxidation of a fuel gas in the presence of the catalyst.
