A hydrocarbon fuel reformer (

200

) is disclosed suitable for producing synthesis hydrogen gas from reactions with hydrocarbons fuels, oxygen, and steam. The reformer (

200

) comprises first and second tubes (

208,218

). The first tube (

208

) includes a first catalyst (

214

) and receives a first mixture of steam and a first fuel. The second tube (

218

) is annularly disposed about the first tube (

208

) and receives a second mixture of an oxygen-containing gas and a second fuel. In one embodiment, a third tube (

224

) is annularly disposed about the second tube (

218

) and receives a first reaction reformate from the first tube (

208

) and a second reaction reformate from the second tube (

218

). A catalyst reforming zone (

260

) annularly disposed about the third tube (

224

) may be provided to subject reformate constituents to a shift reaction. In another embodiment, a fractionator is provided to distill first and second fuels from a fuel supply source.
