- Abstract
Production of ethylene by oxidative coupling of methane (OCM) is a promising direct path from methane to ethylene. Li-W-Mn-O-SiO composite materials prepared by various methods-solid-phase synthesis, silica impregnation, sol-gel synthesis-are used as OCM catalysts. The phase states of these composite materials prepared by the different methods has been studied before and after use in the OCM reaction; the study has unexpectedly revealed the effect of the preparation technique on the phase composition of the material and the specific features of its catalytic behavior in OCM. Optimum catalysts provide an ethylene yield of 15% in terms of passed methane.
