A method for the suppression of soot formation in an autothermal reforming ATR or in a partial oxidation POX reactor

Abstract

A method for the suppression of soot formation during the partial oxidation of a hydrocarbon-containing gaseous feed, in the presence of steam and in an autothermal reforming ATR reactor or in a partial oxidation POX reactor, the method comprising the addition of gaseous carbon dioxide to the hydrocarbon-containing gaseous feed before entry into the reactor. A method for determining a minimum steam to carbon ratio required for soot-free operation is also disclosed.
