Abstract
Methanol is decomposed in the presence of a catalyst containing chromium oxide and zinc oxide as main components and containing a compound of at least one element selected from the group consisting of alkali metals, alkali earth metals and lanthanides, while contents of iron and nickel in the catalyst are each maintained at 0.5% by weight or less. This process is characterized by (1) being excellent in stability at high temperatures, (2) preventing the catalyst from deteriorating, (3) inhibiting the production of by-products, and (4) obtaining a gas in which the CO/H.sub.2 ratio is high.
