OXIDATIVE COUPLING OF METHANE CATALYST AND PREPARATION METHOD FOR SAME |
摘要 |
The present invention discloses a manganese-sodium-tungsten-silicon composite oxide oxidative coupling of methane catalyst containing or not containing titanium, obtained by loading manganese-sodium-tungsten onto a titanium-silicon molecular sieve or a pure silicon molecular sieve by means of a step-by-step impregnation method and calcination. The manganese-sodium-tungsten-silicon composite oxide catalyst containing or not containing titanium has the following structural formula: vMnO2·xNa2O·yWO3·zTiO2·(100-v-x-y-z)SiO2, the v, x, y, and z respectively representing the fractional quality occupied by metal manganese oxide, sodium oxide, tungsten oxide and titanium oxide, 0.3≤v≤16, 0.1≤x≤5, 0.6≤y≤21, 0.0≤z≤4. The manganese-sodium-tungsten-silicon composite oxide catalyst containing or not containing titanium set forth in the present invention is used for oxidative coupling of methane reactions, having excellent low-temperature catalytic activity and ethylene/propylene selectivity generation and reaction stability. |
