Return to Japanese Patent Table of Contents JP7062356 Abstract PURPOSE: To produce economically a liquid hydrocarbon by converting methane at a high carbon availability. CONSTITUTION: The production process comprises the steps of reforming methane and carbon dioxide to form a synthesis gas (in a reactor 1), separating hydrogen from the formed synthesis gas to adjust the molar ratio of the hydrogen to the carbon monoxide of the synthesis gas to a stoichiometric one suitable for a desired FT reaction (Fischer-Tropsh synthesis reaction) (in a hydrogen separator 2), and subjecting the synthesis gas having the adjusted molar ratio to the FT synthesis reaction (in a reactor 3). This process may further comprises the step of removing carbon dioxide and normally vaporous hydrocarbons from the product of the FT synthesis reaction (in a CO2 absorber 5, etc.) and the step of introducing the separated carbon dioxide and hydrocarbons into the reforming step. |
