Patent ID: 7670985

Claim:
An activated carbon supported cobalt based catalyst, comprising 1 to 50 percent by weight of cobalt, based on the activated carbon supported cobalt based catalyst, 10 to 90 percent by weight of an activated carbon carrier, based on the activated carbon supported cobalt based catalyst, and 0.1 to 40 percent by weight of a lanthanum component, and a metal promoter in terms of the metal(s) which is at least one selected from the group consisting of a zirconium component, a cerium component, a chromium component, a vanadium component, a titanium component, a manganese component, a rhenium component, a potassium component, a ruthenium component, a magnesium component and a mixture thereof, based on the weight of the activated carbon supported cobalt based catalyst, wherein the cobalt and the promoter are deposited on the activated carbon carrier or substantially uniformly dispersed therein, and the lanthanum component and the metal promoter are present in the form of a metal, an oxide or a combination thereof, wherein the activated carbon carrier is made from a coconut shell.
