Abstract
A method is described for producing a hydrogen-containing gas mixture from a suitable hydrocarbon-containing feed gas in a reformer, wherein at least part of the feed gas is diverted before it enters the reformer and is supplied to at least one secondary reformer, and wherein the feed gas is contacted with a nanostructured catalyst in the secondary reformer and the substantially CO and CO2 -free exhaust gases of the secondary reformer are either combined with the hydrogen-containing gas mixture which escapes the reformer or introduced into the reformer. Furthermore there is described the use of this method for producing high quality soots, nanoonions, nanohorns, nanofibers and/or nanotubes which adhere to the catalyst, and a device for producing a hydrogen-containing gas mixture from a suitable feed gas in a reformer which comprises a supply line with a super-heated-vapor line joining said supply line, and a discharge line.
