Abstract
A catalyst composition containing cobalt manganese oxide which is modified with silicon in the form of a hydrophilic silica, the catalyst also containing at least one of lanthanum, phosphorus, Fe, Zr, and Zn, and optionally one or more basic elements selected from the group of alkali metal, alkaline earth metal, and transition metals. Also, methods for preparing and using the catalyst composition for producing aliphatic and aromatic hydrocarbons using the catalyst composition.
