        To determine the most effective catalyst for synthesizing petroleum from water gas the influence of TiO₂, CeO₂ and ZrO₂ was examined.  The catalyst containing 3 parts Co, 1 part Cu, and the above oxides was reduced at 300° from the oxides derived from the nitrates.  The gas mixture contained equal parts of CO and H₂ and was passed over 30 gm. of catalyst at 5 liter per hr.  Catalysts containing TiO₂, ZrO₂ or CeO₂ give liquid products at 180°-200° and all show similar gas contractions.  With TiO₂ gas contraction diminishes to 26.1% after 12 hr., then gradually to 40.7% after 39 hr., forming mainly gaseous hydrocarbons.  ZrO₂ is the best, but not as good as MgO.  CeO₂ is the poorest accelerator.
