FIELD: chemistry. ^ SUBSTANCE: method of obtaining hydrocarbons C2-C3 by high-temperature catalytic oxidizing conversion of methane lies in supply to reactor, into which catalyst is placed, and whose free volume is filled with inert filling, of initial gas mixture, which contains mixture of methane and molecular oxygen, at rate 50000-70000 m/g/h, catalyst includes into its composition ions of alkali metal, manganese, tungsten and silicon oxide with molar ratio M:W:Mn:Si, where M-Na or K or Rb or Cs, equal 1.8-2.2:1:1.9-2.3:89-92, and is characterised by presence in it of tungsten in oxidation degree W6+, manganese oxidation degrees Mn7+, Mn6+, Mn3+, catalyst being obtained by thermal processing at 200C and further incineration at temperature 795-799C of initial solid powder-like mixture, consisting of salts and/or oxides of tungsten, manganese, alkali metal and SiO2, taken in said mole ratio in terms per mole of tungsten, manganese, alkali metal and silicon atoms. ^ EFFECT: increase of target product output, catalyst productivity, simplification of technology of obtaining target products and reduction of expenditures. ^ 11 cl, 1 tbl, 30 ex |
