A Study on the Characteristics of Methane Chlorination By Crystalline / Amorphous Carbon

Currently, the petrochemical industry uses naphtha as main raw material. Naphtha has the advantage of being able to produce not only olefin products but also non-olefin products, but it is more expensive than natural gas and coal raw materials. Especially, the domestic petrochemical industry is highly based on basic oil, so it is necessary to reduce the risk through diversification of raw materials. As an alternative plan, C1 gas like methane can be utilized. Methane is a valuable resource which can be used as a basic chemical feedstock or a transportation fuel through chemical conversion processes. And currently, typical and commercialized processes are mostly indirect conversion technologies through synthesis gas, which requires high energy and multi-step process. On the other hand, the direct conversion technology without passing through the syngas has attracted a great deal of attention because it uses low energy and does not require a multi-step process, which is economical. In this study, selective production of methyl chloride was performed by methane chlorination reaction which does not require additional oxygen process. In this study, Crystalline / amorphous carbon was used for the catalysts. The catalysts were characterized by XRD, BET, TEM analysis. The reaction characteristics of the catalysts were invetigated by methane chlorination reaction.
