Abstract
An improved catalyst suitable for use in the production of hydrocarbons from the synthesis gas comprises an iron-containing Fischer-Tropsch catalyst, a zeolite and at least one metal selected from the group consisting of ruthenium, rhodium, platinum, palladium, iridium, cobalt and molybdenum. This catalyst gives a high CO conversion and hydrocarbons enriched with C.sub.5.sup.+ gasoline fraction.
Claims15
A catalyst for the production of hydrocarbons from the synthesis gas, which comprises the combination of an iron-containing Fischer-Tropsch catalyst, a zeolite and at least one metal selected from the group consisting of ruthenium, rhodium, platinum, palladium, iridium, cobalt and molybdenum, said metal being supported upon the iron-containing Fischer-Tropsch catalyst or supported upon a mixture of the iron-containing Fischer-Tropsch catalyst and the zeolite, wherein the iron in terms of iron oxide in the iron-containing Fischer-Tropsch catalyst is present in an amount of 5 to 80% by weight, based on the combined weight of the iron oxide and zeolite, and wherein the metal is present in amounts of 0.3 to 5% by weight, based upon the combined weight of the iron oxide and the zeolite.
A process for the production of a catalyst, which comprises mixing intimately a high silica zeolite with a Fischer-Tropsch catalyst and then impregnating the mixture with a solution containing at least one metal salt selected from the group consisting of salts of ruthenium, rhodium, platinum, palladium, iridium, cobalt and molybdenum.
