Abstract:
1. An unreduced catalyst consisting of cobalt species, zinc oxide, and aluminium, and optionally one or more promoters selected from the group consisting of magnesia, ceria, lanthana, titania, zirconia, hafnia, ruthenium, platinum, palladium, rhenium, and a combination thereof, wherein the cobalt species are intimately mixed with aluminium containing zinc oxide in which the aluminium is in the form of at least one of alumina or ZnAl 2 O 4 , the aluminium is present in an amount of about 10-66% by weight (based on ZnO) and the cobalt species are present in an amount such that when the catalyst precursor is reduced to form a reduced catalyst the cobalt content is about 15-75% based on the reduced catalyst, and when the catalyst precursor is reduced at 425° C., the reduced catalyst has a cobalt surface area as measured by hydrogen chemisorption at 150° C. of at least 20 m 2 /g of cobalt.
