The reaction was carried out at theatmospheric pressure at temperature range 700-780 °C, using Cu-Fe/Al 2 O 3 , Cu-Mo/Al 2 O 3oxide catalysts. The conversion and selectivity of reaction products strongly depends onreaction conditions. We have found that methane was transformed to methanol, COx, H 2 , H 2 Oand to formaldehyde. It was found that increasing the temperature increased CH 2 O selectivityand decreased CH 3 OH selectivity.The physico-chemical properties of the catalyst were detected before and after reactionusing different techniques: N 2 adsorption, SEM, DRX and FTIR.Keywords: Selective oxidation; Methane; Methanol; Formaldehyde.445
