Abstract
A catalyst suitable for use in catalytic shift, or methanol synthesis, comprises copper, zinc oxide, magnesia, and at least one trivalent metal oxide, e.g. alumina. The amount of magnesia is such that the magnesium atoms constitute 0.2 to 7% of the total number of copper, zinc, and magnesium atoms.
Claims4
A catalyst precursor comprising an intimate mixture of finely divided oxidic materials and consisting essentially of copper oxide, zinc oxide, alumina, and magnesia, the proportion of magnesia being such that the magnesium atoms constitute 1.1 to 7% of the total number of copper, zinc and magnesium atoms in the precursor, and the proportion of alumina being such that the aluminum atoms constitute 3 to 30% of the total number of copper, zinc, aluminum, and magnesium atoms in the precursor.
