METHOD AND DEVICE FOR SYNTHESIZING METHANE GAS USING CARBON DIOXIDE AND HYDROGEN AT ROOM TEMPERATURE AND AT ATMOSPHERIC PRESSURE

摘要

The present invention relates to a method and device for synthesizing a methane gas using carbon dioxide and hydrogen at room temperature and at atmospheric pressure and, more specifically, to a method for synthesizing methane (CH₄), which is a synthetic natural gas, only by means of carbon dioxide (CO₂) and hydrogen (H₂) by using a catalyst-dielectric barrier discharge (DBD) plasma at room temperature and at atmospheric pressure. The method and device for synthesizing a methane gas according to the present invention have effects capable of synthesizing a methane gas (CH₄), which is a synthetic natural gas, only by means of carbon dioxide (CO₂) and hydrogen (H₂) by using a catalyst-dielectric barrier discharge (DBD) plasma at room temperature and at atmospheric pressure. Moreover, the synthesizing method and device for a methane gas according to the present invention has the advantages of not only low production costs due to not using separate heating equipment and pressurizing equipment for performing a methane gas synthesizing process, but also high added value due to not involving danger when performing a process.
