Abstract

Non-oxidative coupling of methane with high selectivity into ethane (>99% among hydrocarbon) in a classical fixed-bed reactor catalysed by SiO₂–Al₂O₃ or γ-Al₂O₃ supported tungsten hydride is presented. Continuous hydrogen separation, using a Pd–Ag membrane in a fixed-bed reactor, led to methane coupling far beyond the thermodynamic equilibrium conversion.
