Abstract
Abstract Hydrogen containing gas is produced by reacting a hydrocarbon, hydrocarbon derivative with steam and/or, where appropriate, carbon dioxide, in the presence of a catalyst supported on a metal or alloy resistant to the conditions in which the reaction is carried out. Synthesis of methanol or purification of hydrogen by methanation of carbon oxides contained in it can also be carried out using such a catalyst. The support is suitably a chromium steel, of a grade depending on process temperature. Preferably the metal or alloy carries also an oxidic secondary support layer such as alumina. The catalyst is preferably in the form of small, random-packed, honeycombs.
