  • Preparation of Pb-substituted hydroxyapatite catalyst and use in oxidative coupling of methane
    Patent number: 5877387
    Abstract: A preparation of a Pb-substituted hydroxyapatite catalyst for oxidative coupling of methane represented by the formula Ca.sub.10-x pb.sub.x (PO.sub.4).sub.6 (OH).sub.2 wherein 0<X<10 or preferably 0<X<3, includes dissolving calcium nitrate tetrahydrate ?Ca(NO.sub.3).sub.2 4H.sub.2 O!, lead nitrate ?Pb(NO.sub.3).sub.2 ! and monobasic ammonium phosphate ?NH.sub.4 H.sub.2 PO.sub.4 ! 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 C.sub.2 compounds using the thusly produced catalyst includes reacting a mixed gas composed of methane, oxygen and helium in the presence of 5.about.20 g.multidot.min/L of the Pb-substituted hydroxyapatite catalyst according to the present invention, at a high temperature of at least 600.degree. C.
