摘要： A method and apparatus for introducing an oxidant mixed with a carrier gas into pre-heating zone of a continuous furnace for effectively removing lubricant from powder metal compacts prior to sintering at high temperatures. Mixing a controlled amount of a gaseous oxidizing agent such as moisture, carbon dioxide, air or mixtures thereof with a carrier gas and introducing the mixture into the preheating zone of a continuous furnace under controlled conditions accelerates removal of lubricant from powder metal compacts prior to sintering at high temperature by decomposing lubricant vapors into smaller and more volatile hydrocarbons, produces sintered components with close to soot- and residue-free surfaces and with the desired physical properties, prolongs the life of furnace components including muffles and belts, and reduces downtime, maintenance and operating costs.

摘要： A method for controlling NOx in a multi-zone re-heating furnace used for meeting process heating (or re-heating) requirements in the metals industry. Oxidant-fuel stoichiometry is altered in different zones of a multi-zone re-heating furnace to reduce the overall NOx emission without replacing existing burners or intrusively modifying the furnace (or drilling holes in the furnace) for fuel and/or an oxidant injection. The oxidant-fuel stoichiometry in at least one zone of a multi-zone re-heating furnace is made either oxidant neutral or oxidant deficient (or fuel rich) to reduce the formation of NOx and the oxidant-fuel stoichiometry of at least one other zone that is located downstream of the oxidant neutral or oxidant deficient zone is made oxidant rich (or fuel lean) to further reduce the formation of NOx in the furnace.

摘要： In a process for producing a hydrogen-containing gas, a hydrocarbon feed gas and steam are introduced into a reaction vessel containing a complex metal oxide and steam-hydrocarbon reforming catalyst thereby forming a combustible gas mixture comprising hydrogen. A regeneration gas comprising greater than 0.1 volume % oxygen up to and including 2 volume % oxygen is introduced into the reaction vessel to displace at least a portion of the combustible gas mixture from the reaction vessel. Subsequently, additional regeneration gases may be introduced into the reaction vessel. Numerous means for providing various regeneration gases are presented.
