A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a sulfur tolerant precious metal and a non-sulfating carrier so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low sulfur reformate is collected, and contacting the sulfur tolerant catalyst with an oxygen containing gas to convert at least a portion of adsorbed sulfur to a sulfur oxide that is desorbed from the sulfur tolerant catalyst.

Reforming sulfur-containing hydrocarbons using a sulfur resistant catalyst

A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a non-sulfating carrier and one or more of a sulfur tolerant precious metal and a non-precious metal compound so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low sulfur reformate is collected, and contacting the sulfur tolerant catalyst with an oxygen containing gas to convert at least a portion of adsorbed sulfur to a sulfur oxide that is desorbed from the sulfur tolerant catalyst.

An OBD system is provided for monitoring an ozone depletion system that includes a catalyst coating containing MnO applied to a heat exchange surface on a moving vehicle over which atmospheric air passes. A physical characteristic of the catalyst coating or a material containing a physical characteristic within the catalyst coating is sensed to determine the presence or absence of the catalyst coating for detecting catastrophic failure of the ozone depleting system and/or degradation or wear of the catalyst coating to ascertain the efficiency of the catalyst coating.

System for sensing catalyst coating loss and efficiency

A method for operating a palladium oxide containing catalytic combustor useful, e.g., for powering a gas turbine, wherein the palladium oxide is supported on a metal oxide such as alumina, ceria, titania or tantalum oxide. The method involves maintaining control of the temperature within the combustor in such a manner as to insure the presence of palladium oxide. By maintaining the temperature below about 800.degree. C. decomposition of palladium oxide into metallic palladium is avoided and high catalytic activity is retained. Regeneration of catalyst following inactivation resulting from an over-temperature is accomplished by using a heat soak in a temperature range which varies depending on the metal oxide used to support the palladium oxide.

C. decomposition of palladium oxide into metallic palladium is avoided and high catalytic activity is retained. Regeneration of catalyst following inactivation resulting from an over-temperature is accomplished by using a heat soak in the temperature range of about 530.degree. C.-650.degree. C.
