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 provides a hyper-branched polymer having a three-dimensional structure, which is applicable to treatment of harmful substances in the atmosphere and has antibacterial activity, as well as a method for manufacturing the same. Further, the present invention provides an antibacterial spherical activated carbon which is ultimately obtained using the hyper-branched polymer as a precursor. The antibacterial spherical activated carbon, which is the final product according to the present invention, may induce a chemical bonding of ion bonds in an antibacterial component to a carrier without use of a separate binder, thereby stably immobilizing the antibacterial component. Furthermore, it is possible to adjust a loading amount of the antibacterial component as well as a specific surface area of the carrier through a simple operation. Moreover, the present invention enables uniform distribution of the antibacterial component on the spherical activated carbon at the atomic level, and has an advantage in that a high-strength antibacterial spherical activated carbon can be manufactured without elution and/or loss of antibacterial component even when using the activated carbon of the present invention for water treatment. Furthermore, effects of increasing the antibacterial performance by adsorption of organic matter in pores of the activated carbon that has been developed through incompatibility processing-carbonization-activation processes may also be expected. Therefore, the antibacterial spherical activated carbon prepared by the present invention is applicable to not only the removal of harmful substances such as SOx, NOx, VOC, etc. in the atmosphere but also an air purifier using antibacterial ability of the antibacterial material itself. In particular, the present material can be applied to all air cleaning systems requiring antibacterial functions because a large amount of antibacterial component can be uniformly supported on the spherical activated carbon, and eventually, the material has a perfectly spherical shape with a uniform surface and high strength so as to attain high organic matter removal efficiency.
