Comparison of Pyrogen of Thermal Diffusion Reactor in Dehydrogenative Coupling of Methane

Abstract

Dehydrogenative coupling of methane in the thermal diffusion reactor was carried out, using a carbon rod and a tungsten wire as pyrogens. Pyrogens were studied of durability, reaction activity and electric power required. Three results were obtained. 1) 3.0mm of carbon rod made from carbon black and artificial graphite exhibits high persistence at high reaction temperature. 2) The reaction rate of methane per surface area of carbon rod used as pyrogen is same as that of tungsten wire. 3) At the limit temperature of pyrogen reuse, the electricity consumption of carbon rod for getting the specified activity is about 1.7 times that of tungsten wire.
