Improved process for the catalytic gas phase preparation of low molecular weight (C2-6) olefinic hydrocarbons from mixtures of H2 and CO, the improvement consisting of contacting and reacting a mixture of H2 and CO, at a H2/CO molar ratio within the range 0.3 to 1.5, at a space velocity of 1 to 100 minutes-1, at a pressure of 1 to 2000 psia (6.894 kPa to 13.788 MPa), at a temperature within the range 200 DEG to 400 DEG C., in the presence of the catalyst of the empirical formula AB1-aFeaO3, wherein A, B and a are defined herein, for example, LaFeO3.
