Methanol decomposition in a water-methanol equimolar mixture on a nickel-promoted copper-zinc-cement catalyst

Methanol decomposition in a water-methanol equimolar mixture is studied in the presence of a nickel-promoted copper-zinc-cement catalyst. Methanol dec omposition at 200-300 degreesC on the oxide and reduced forms of the cataly st yields a gas with an H-2/CO ratio close to two. The use of an equimolar CH3OH-H2O mixture under analogous conditions enables obtaining gaseous prod ucts with a hydrogen concentration up to 75 vol %.
