OP-II-3

PP-II-10The experiments were provided under atmospheric pressure of the pure methane(99.99%) in temperature interval 475 – 525 K. The tube from the alloy of palladiumwith 5 mass.% of ruthenium was placed inside the reactor. The length of a tube was1 m, with diameter 1 mm and wall thickness 0.05 mm. The results have shown thepossibility of the realization non oxidative methane coupling with non thermicactivation of CH 4 molecules.The maximum methane conversion was obtained when through the palladiumalloy tube, placed inside a reactor filled by methane, was given argon flow, by meansof which hydrogen moved from the reaction zone, where it was formed as the resultof methane coupling. So the methane conversion under the temperature 430 Kincreased from 1.3 %, obtained under the same temperature without hydrogenremoving, to 5.2 % when hydrogen was removing through a membrane catalyst(Table 1). The main of the reaction products was propane and ethane with smallquantity of the ethylene, identified at conversion above 1%.Table 1.
