VERFAHREN ZUR METHANOLSPALTUNG.

摘要

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 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 characterised 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/H2 ratio is high.
