Abstract

Abstract: The thermal decomposition of methane was investigated in a plug flow reactor at 1273 K and 1 bar. The methane feed was diluted with helium (He:CH4 = 2:1). The study was carried out at low conversion of methane ( <1%). A mechanistic simulation model was developed. The kinetic scheme consists of 35 reversible free radical reactions and one irreversible free radical reaction. The model explains the formation and consumption of CH4, C2H6, C2H4, C2H2, C3H6, a-C3H4, (allene) and p-C3H4 (propyne). A sensitivity analysis was performed to find the main free radical reactions in the formation and consumption of the reported products. The autocatalysis phenomenon in the decomposition of methane was studied and no such effect was observed.
