Abstract:
A catalyst bed unit employing measured amounts of cobalt in conjunction with platinum forms the fuel reactive catalyst of the unit to render the heater with which the unit is associated capable of operation at low carbon monoxide emission levels. The catalyst is applied to the support therefor by dissolving chloroplatanic acid and cobalt nitrate in a solution of methanol and water, spraying the mixture onto the support, and heating the unit to reduce the chloroplatanic acid and cobalt nitrate to platinum and cobalt metals.
