K₂CO₃ greatly increased the mean molecular weight of the product, as did Cu to a lesser degree. The effect of adding H₃BO₃ and Mn was the reverse. However, the effect of these substances on the production of gasol (mixture of C₂H₆, C₃H₈ and C₄H₁₀) was not very marked, so that it was not possible to improve the production of gasol by the addition of these substances alone. On the contrary, the elevation of the temperatures of the synthesis had a remarkable effect in increasing the yield of gasol. Of the various catalysts used 100 Fe+125 kieselguhr gave the best results, yielding a product containing 78% gasol, although this catalyst had less power of causing CO and H₂ to react.
