    • A catalyst bed (30) for a combustor (18) for supporting the catalytic combustion of a gaseous air/fuel (e.g., methane or natural gas) combustion mixture contains an igniter catalyst member (1) upstream of a promoter catalyst member (2). The catalyst members each comprise carrier monoliths, the igniter catalyst member (1) having an igniter catalyst material deposited thereon and the promoter catalyst member (2) having a promoter catalyst material deposited thereon. The igniter catalyst material is distinguished from the promoter catalyst material in one or more of the following ways: the igniter catalyst material may have (a) a higher catalytic activity for combustion of the air/fuel mixture, (b) a lower catalyst deactivation temperature than the promoter catalyst material, and/or (c) the promoter catalyst regeneration temperature range brackets the upper limit of the regeneration temperature range of the igniter catalyst.

    • A multistage catalytic partial oxidation (CPO) process for oxidizing a hydrocarbon feedstream comprising C1-C4 hydrocarbons, with an oxygen-containing feedstream to produce a product comprising CO and H2, also known as synthesis gas or syngas. The process employs a CPO catalyst, and controlled process features, including: (A) the total oxygen requirement for the process is introduced incrementally, in more than one reaction stage, using an oxygen-containing feedstream at more than one feed point in the process, each stage including a catalyst; (B) the oxygen-containing feedstream, hydrocarbon feedstream and, in reaction stages after the first of said multiple stages, the intermediate product produced in the prior stage, are mixed for a period of time, after they are brought into contact with one another, of less than about 1 millisecond to form a substantially uniform mixture, wherein the mixture is then contacted with the catalyst; (C) the oxygen-containing feedstream and the hydrocarbon feedstream are preheated prior to entry into the first stage, to a temperature of from about 450° C. to less than about 1,000° C.; and (D) the mixture temperature of the product in each stage following the first stage is from greater than about 600° C. to less than about 1,000° C. Preferably, the process comprises less than or equal to about five stages, the first stage preheat temperature recited in step (C) is greater than about 550° C. and the mixture temperature of the product in each stage following the first stage is at least 700° C.
