Methane conversion to higher hydrocarbons by UV irradiation / Alan R. Derk in Industrial & engineering chemistry research, Vol. 47 N°17 (Septembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°17 (Septembre 2008) . - p. 6568–6572 Titre : Methane conversion to higher hydrocarbons by UV irradiation Type de document : texte imprimé Auteurs : Alan R. Derk, Auteur ; Hans H. Funke, Auteur ; Falconer, John L., Auteur Année de publication : 2008 Article en page(s) : p. 6568–6572 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Methane  conversion  UV  photolysis  Radio-frequency-powered  Kr/Ar  discharge  lamp Résumé : The potential for using UV photolysis to convert methane to higher hydrocarbons with high yields was demonstrated with a radio-frequency- (RF-) powered Kr/Ar discharge lamp (λ = 116.5 and 123.6 nm, flux = 3.3 × 1014 photons/s) at pressures of 47 and 93 kPa and at ambient temperature. The highest conversion was 39%. Photon yields for carbon−carbon bond formation were as high as 4.5. The main reaction products were hydrogen, ethane, propane, and n- and i-butane, but smaller amounts of ethylene and higher alkanes were also detected. The hydrocarbon products followed a Flory distribution.
