Abstract: The present invention relates to a catalyst for oxygen-free direct conversion of methane and a method of converting methane using the same, and more particularly to a catalyst for oxygen-free direct conversion of methane, in which the properties of the catalyst are optimized by adjusting the free space between catalyst particles packed in a reactor, thereby maximizing the catalytic reaction rate without precise control of reaction conditions for oxygen-free direct conversion of methane, minimizing coke formation and exhibiting stable catalytic performance even upon long-term operation, and to a method of converting methane using the same.

Abstract: The present disclosure relates to a method for non-oxidative direct conversion of methane. Specifically, in the method, a methane/hydrogen gas is introduced into an Inconel 600 reactor at a superficial velocity of 100 to 200 cm·min−1 and a catalyst is not externally introduced into the reactor. Under the conditions, a non-oxidative direct methane conversion reaction is performed in the Inconel 600 reactor. The method maximizes the reaction rate, minimizes coke formation, and increases the yields of C2 hydrocarbon compounds and aromatic compounds.

Abstract: Disclosed is a method for directly synthesizing monocyclic aromatic compounds and long-chain olefin compounds from a carbon dioxide-rich synthetic gas and, specifically, a method for directly synthesizing monocyclic aromatic compounds and long-chain olefin compounds from a carbon dioxide-rich synthetic gas, the method comprising a step of preparing a C1-C15 short-chain hydrocarbon by Fischer-Tropsch (FT) synthesis and a step of preparing monocyclic aromatic compounds and long-chain olefin compounds by dehydrogenating the short-chain hydrocarbon products, and maximizing the yield of the short-chain hydrocarbon by using, as a synthetic gas to be used in FT synthesis, a carbon dioxide-rich synthetic gas in which the molar ratio of hydrogen, carbon monoxide and carbon dioxide is delimited to a specific range, and maximizing the yield of the monocyclic aromatic compounds or the long-chain olefin compounds by specifying the composition of a catalyst to be used in the dehydrogenation and the temperature and pressure condition.
