Abstract
New catalysts containing a Group VIII metal such as iron, a Group IIB metal, such as zinc, a Group IA alkali metal such as potassium, rubidium and/or cesium, and a lanthanide metal, such as cerium, exhibit improved productivity in synthesis of alpha-olefins from hydrogen rich synthesis gas.
