摘要： High activity steam reforming iron oxide catalysts are described. Such catalysts can be unsupported utilizing at least 90% by weight iron oxide and various modifiers (Al.sub.2 O.sub.3, K.sub.2 O, CaO, SiO.sub.2) or unmodified and supported on such things as alumina, CaO impregnated alumina, and lanthanum stabilized alumina. When used in steam reformers such as autothermal and tubular steam reformers, these catalysts demonstrate much improved resistance to carbon plugging.

摘要： High activity steam reforming catalysts are described particularly adapted for use in autothermal reforming processes. A rhodium catalyst on a calcium oxide impregnated alumina substrate allows the autothermal reforming process to take place with substantially no carbon plugging at oxygen to carbon ratios below what had been considered critical for avoiding carbon plugging of the catalyst in the past.

摘要： A catalytic combustor bed configuration particularly adapted for use in wood and coal burning stoves is described comprising a support screen having a layer of fully catalyst impregnated particulate material next to the screen, a layer of particulate material catalyzed on its outer surface next to the layer of fully impregnated material and a layer of uncatalyzed particulate material next to the outer surface catalyzed material. Optionally, a layer of uncatalyzed particulate material may be used between the screen and the fully impregnated particulate material. Such an arrangement, in addition to making maximum utilization of the catalyst material, also minimizes pressure drop across the catalytic combustor.

摘要： A heat exchanger uses the heat from processed fuel gas from a reformer for a fuel cell to superheat steam, to preheat raw fuel prior to entering the reformer and to heat a water-steam coolant mixture from the fuel cells. The processed fuel gas temperature is thus lowered to a level useful in the fuel cell reaction. The four temperature adjustments are accomplished in a single heat exchanger with only three heat transfer cores. The heat exchanger is preheated by circulating coolant and purge steam from the power section during startup of the latter.

摘要： In the hydrotreating and steam reforming of an oxygen and sulfur bearing hydrocarbon fuel the oxygen is first removed in an oxidizer containing a bed of platinum catalyst, the inlet temperature being well below 1000.degree. F. and preferably on the order of 300.degree. F. The sulfur in the fuel does not harm the oxidizer catalyst and may be removed downstream by known hydrodesulfurization techniques prior to reforming.
