With Fe catalysts pressure increases the life of catalyst, and increases the total rate of reaction; the yield of gasol approaches 30 l. per m.³ Increase in the gasol yield is not attainable by greater elevation of temperature. The optimum temperature is 270°-320°. The effect of pressure is comparatively complex. Raising the pressure increases the tendency to form higher hydrocarbons as well as lower hydrocarbons, especially CH₄ and C₂H₆, because of an increase in the reactivity of H₂. This fact is interpreted to be a peculiarity in the mechanism of the synthesis under pressure. Therefore, gasol synthesis in which a high degree of unsaturation is desired should be carried out with a catalyst containing white clay as the carrier or by adding K₂CO₃ to a catalyst containing acid clay or active clay to promote the adsorption of CO. By raising the temperature it is impossible to increase the yield of gasol without also raising the yield of CH₄, as is the case at ordinary pressure.
