FIELD: chemistry.

SUBSTANCE: described is a method of preparing a catalyst for oxidative condensation of methane to C₂₊ hydrocarbons, which involves depositing manganese and sodium tungstate on a silicon dioxide support via successive impregnation thereof with aqueous solutions of manganese nitrate and then sodium tungstate, followed by calcination in air at temperature of 800°C, wherein the obtained composition Mn - Na₂WO₄/SiO₂ with total content of manganese of 1-2 wt % and sodium tungstate of 3-5 wt % is mixed with an inert material which actively absorbs microwave energy, based on a metal carbide with weight ratio of components of 2-4:1, respectively. Described is a method for oxidative condensation of methane to C₂₊ hydrocarbons in the presence of a catalyst obtained using the method described above.

EFFECT: high conversion of methane and high selectivity with respect to C₂₊ hydrocarbons.
