PURPOSE: To produce hydrocarbons with high efficiency by pretreating catalyst layers of catalysts consisting of Co and La with the gaseous H2 fed therein and feeding gaseous raw materials consisting of CO and H2 thereto.

CONSTITUTION: Catalysts are composed of Co and 5-80 wt% La based on the weight of the Co, and are deposited on diatomaceous earth, alpha-alumina, alumina-magnesia spinels, etc. These catalysts are pretreated with the gaseous H2 fed therein for 30min-8hr under the conditions of 300-400oC and <= 10 kg/cm2 gaseous H2 pressure. Raw material gases consisting of CO and H2 are fed into said catalysts under 5-10 kg/cm2 reaction pressure at 200-300oC reaction temp. after the pretreatment, whereby hydrocarbons are synthesized.
