Popis:	The methane and propylene oxidative conversion over Na 2 O/ZnO systems - with ultrasonic treatment (UST) during preparation and without preparation - was studied. Methane oxidative coupling has been also studied over a number of oxide catalysts: Pb/ aerosil, ZnO and 10%Na 2 O/ZnO, with the mixtures of CH 4 -O 2 and CH 4 O 2 H 2 O 2 . It has been shown that a pulse introduction of H 2 O 2 vapours into the methane-oxygen mixture enables to increase the yield of C 2 hydrocarbons and to stabilize a state of surface. The positive influence of the UST on catalytic activity has been established too.
