Cerium promoted fischer-tropsch catalysts

摘要

New Fischer-Tropsch catalysts containing a Lanthanide Group element, such as cerium, exhibit improved activity over conventional catalysts and exhibit a reversal in the olefin/paraffin ratio of low molecular weight hydrocarbons. The catalyst comprises: (a) a Group VIII metal oxide; (b) a Group IIB metal oxide; (c) a Group IVB and/or VIIB metal oxide; (d) a Group IA metal oxide; and, (e) a Lanthanide group metal oxide.
