摘要： Lanthanide-promoted rhodium-containing supported catalysts that are active for catalyzing the net partial oxidation of methane to CO and H2 are disclosed, along with their manner of making and high efficiency processes for producing synthesis gas employing the new catalysts. A preferred catalyst comprises highly dispersed, high surface area rhodium on a granular zirconia support with an intermediate coating of a lanthanide metal and/or oxide thereof and is thermally conditioned during catalyst preparation. In a preferred syngas production process a stream of methane-containing gas and O2 is passed over a thermally conditioned, high surface area Rh/Sm/zirconia granular catalyst in a short contact time reactor to produce a mixture of carbon monoxide and hydrogen.

摘要： Embodiments include a method and apparatus for converting a hydrocarbon and oxygen feed stream to a product stream such as syngas, including multiple serially aligned reaction zones and multiple hydrocarbon feeds. The first reaction zone catalyzes the net partial oxidation of the feed hydrocarbon. The subsequent zones catalyze reactions such as the stream or dry reforming of hydrocarbons or the water gas shift reaction, depending on the stream composition in the vicinity of the zone, and the desired product stream composition.

摘要： Controlled pore structure catalysts are disclosed that are active for catalyzing the partial oxidation of methane to CO and H2 and, advantageously, are capable of initiating the reaction without the need for an additional ignition source. A preferred catalyst comprises rhodium and samarium supported on an alumina or modified alumina support having certain surface area, pore volume, pore size and metal dispersion characteristics that permit light-off of the reaction at temperatures below 500° C. and with little or no use of an ignition agent. A method of partially oxidizing a light hydrocarbon to form synthesis gas, and a method of enhancing low-temperature light-off of the process are also described.

摘要： A pretreatment method for increasing the average pore size of a catalyst support is disclosed which increases the diffusivity and effectiveness factor η. The pretreatment method includes calcining the support in moisturized air at an elevated temperature sufficient to increase the average pore size. In some embodiments, the support may be treated with an acidic/basic solution prior to the calcination step. Alternatively, the calcination step may occur in a gas mixture including water/air/acidic (or basic) gases.

摘要： The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. One embodiment of the re-dispersion technique involves the treatment of a deactivated syngas catalyst with a re-dispersing gas, preferably a carbon monoxide-containing gas such as syngas. If necessary, the catalyst is then exposed to hydrogen for reduction and further re-dispersion.
