Abstract
A catalytic refractory heating appliance includes a body formed from a silicon carbide refractory material having a porosity that permits ionic oxygen to pass through the refractory material. The body defines a gas flow channel. A catalyst coating is on a surface of the refractory material of the body, whereby the refractory material becomes an active component with catalytic capability. For example, when the catalytic refractory heating appliance is a fire tube carbon dioxide and sulfur compounds can be directly absorbed, or carbon monoxide is reduced to methane.
Claims14
A catalytic refractory heating appliance, comprising:
- a body formed from a silicon carbide refractory material having a porosity that permits ionic oxygen to pass through the refractory material, the body defining a gas flow channel;
- and
- a catalyst coating a surface of the refractory material of the body, whereby the refractory material becomes an active component with catalytic capability.
A catalytic refractory heating appliance, comprising:
- a body formed from a conductive nitride-bonded silicon carbide refractory material having a porosity that permits ionic oxygen to pass through the refractory material, the body being tubular and defining a gas flow channel;
- and
- a metal oxide framework catalyst coating a surface of the refractory material of the body, whereby the refractory material becomes an active component with catalytic capability.
