METHOD OF DIRECT SYNTHESIS OF LIGHT HYDROCARBONS FROM NATURAL GAS

摘要

The present invention relates to a method of direct synthesis of light hydrocarbons from natural gas and carbon dioxide capable of improving production yield of light hydrocarbons and carbon utilization efficiency through a series of process of preparing synthesis gas with a predetermined molar ratio of carbon monoxide and hydrogen by a combined steam reforming of natural gas and carbon dioxide reforming of methane, performing Fischer-Tropsch reaction of the prepared synthesis gas in the presence of a specific catalyst, and recycling the byproducts of methane and carbon dioxide as the source material of the combined reforming.
