        Experiments substantiated the authors’ proposed mechanism for Fischer-Tropsch synthesis.  The reaction vessel of Terex glass was made double walled so that the gas mixture, CO+2H₂, led in could be heated before entering the catalyst zone.  The catalyst used was made of Co, CeO₂, ThO₂, B₂O₃, and diatomaceous earth.  The reaction was run at 200° at the rate of flow 4 l. per hr.  The reaction products were collected in 2 traps, condensed by water and solids CO₂-C₂H₅OH mixture, respectively.  The gas contraction and oil yield were not parallel unless the reaction was normalized.  In the initial stage CH₄ formation predominated, cutting down the oil formation, but as time proceeded side reactions other than oil formation were inhibited.  Physicochemical properties of the reaction products are tabulated.  The catalyst used proved to be very durable.
