Direct Nonoxidative Conversion of Methane to Ethylene ...

May 09, 2014 Direct conversion of CH 4 is potentially more economical and environmentally friendly but is challenging because CH 4 exhibits high C–H bond strength (434 kJ/mol), negligible electron affinity, large ionization energy, and low polarizability ().In the pioneering work of Keller and Bhasin in the early 1980s, CH 4 was activated with the assistance of oxygen ().
