        Synthesis of liquid hydrocarbons from CO and H₂ is studied.  For catalysts that require no high temperature before reduction of CO with H₂ and cause reaction at approximately 200°, no accelerating action of the carrier is noticed, but it has a tendency to decrease the activity of the catalyst.  For catalysts that require high temperatures before the reaction, the presence of carrier gives much acceleration, increases the resistance to heat, and increases the activity of the catalyst.  There is no fundamental difference between carrier and accelerator in increasing the resistance of the catalyst to heat. The temperature of reduction increases with an increase in amount of carrier and accelerator, and an increase in small amount of accelerator gives the result of using a large amount of carrier when it is estimated by an increase in the temperature of reduction.
