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: The present invention relates to a catalyst for selective hydrogenation of acetylene and a preparation method thereof. More specifically, the catalyst and preparation method maximize the catalytic reaction rate at various reaction temperatures and suppress side reactions to minimize the generation of green oil and cokes and to improve the deactivation rate of a catalyst when preparing ethylene from acetylene. Thus, the catalyst and the preparation method provide a high conversion rate of acetylene and a high ethylene production yield.
