Abstract PURPOSE: To prepare hydrocarbon in good yield, by using cobalt and lanthanum oxide as components of a catalyst for reducing carbon monoxide with hydrogen to synthesize hydrocarbon. CONSTITUTION: As a catalyst for hydrocarbon synthesis for synthesizing hydrocarbon such as methane by reducing carbon monoxide with hydrogen, cobalt and lanthanum oxide are used. This catalyst can reduce carbon monoxide with hydrogen in high efficiency and can prepare 1c or more hydrocarbon such as methane or ethane in good yield and is also excellent in selectivity. |
