Abstract
The invention relates to a catalyst for conversion of methanol, ethanol alone or in combination with n-propanol to isobutanol. The catalyst is a noble metal supported on at least a first phase having poorly crystalline manganese and zinc doped zirconium oxide phase containing about 71 to about 91 atomic % zirconium, about 10 to about 16 atomic % manganese and about 4 to about 8 atomic % zinc and a second phase of irregularly shaped hetaerolite-like crystals containing about 65 to about 69 atomic % manganese, about 31 to about 35 atomic % zinc and zero to about 5 atomic % zirconium embedded in the first phase. The catalyst is useful in making isobutanol.
