When a mixture (I) of 32.8% CO, 65% H₂ and 2.2% N₂ was passed at the rate of 4 l./hr. over a 27-cm. contact layer of catalyzer (Ni+15% Mn+3% ThO₂+125% kieselguhr) containing 2.5 gm. Ni at 200°, 117 cc. of liquid benzine per m.³ of pure CO+2H₂ was obtained. Under the same conditions (I) containing approximately 10% N₂ gave 115 cc., 10% CH₄ 120 cc., 10% CO₂ 111 cc., 20% N₂ 112 cc., 20% CH₄ 106 cc., 20% CO₂ 91 cc., 40% N₂ 95 cc., 40% CH₄ 85 cc. and 40% CO₂ 90 cc. Thus less than 20% of inert gas did not seriously affect the reaction but 40% cut the yield considerably. Also the more the mixture was diluted, the lighter and more volatile was the oil produced. After removing the S compound and CO₂ from a commercial gas it was passed over a 47-cm. layer of catalyzer containing 3.5 gm. Ni under the above conditions. This gas (30.2% CO, 54% H₂, 4.7% CH₄, 10.9% N₂), containing 81% usable CO+2H, gave 98 cc. benzine/m.³ of gas or 121 cc./m.³ of pure CO+2H. Under like conditions (I) gave 137 cc./m.³ of pure CO+2H.
