PREPARING METHOD OF PB-SUBSTITUTED HYDROXYAPATITE CATALYST FOR METHANE DIMERIZATION |
| 摘要 |
A preparation of a Pb-substituted hydroxyapatite catalyst for oxidative coupling of methane represented by the formula Ca10-xpbx (PO4)6(OH)2 wherein 0<X<10 or preferably 0<X<3, includes dissolving calcium nitrate tetrahydrate [Ca(NO3)24H2O], lead nitrate [Pb(NO3)2] and monobasic ammonium phosphate [NH4H2PO4] in a distilled water at room temperature to have over 0.01M concentration and pH 9 and maintaining a resultant precipitate for 5 to 20 hours for aging and then calcining the resultant. A method for producing C2 compounds using the thusly produced catalyst includes reacting a mixed gas composed of methane, oxygen and helium in the presence of 5 DIFFERENCE 20 gxmin/L of the Pb-substituted hydroxyapatite catalyst according to the present invention, at a high temperature of at least 600 DEG C. |
