The partial oxidation of methane to methanol was studied. The effectof various homogeneous "sensitizers" on the oxidation of pure methane was e-valuated at 433℃ and under a pressure of 5.0MPa. It was found that CH3NO2was the best one among them. A kinetic study in the presence of CH3NO2wascarried out and the reaction mechanism was discussed.

Ketone was the optimum sensitizer selected from many additives. With ketonc as the additive, the yield of formaldehyde was more than 2.40% and the highest yield Was 3.58% over the silica gel-1 catalyst, and remained almost unchanged during the catalyst life test of 500 h. Ketone can compensate the catalyst for the -OH loss shown by 1R, TGA and XPS of the catalysts before and after the reaction.

The effect of phosphorus addition to silica for Partial oxidation of methane was studied. The results showed that the formaldehvde selectivity was improved as the result of phosphorus addition to silica and that the optimum phosphorus pentoxide contcnt on silica was 1.5%. The role of phosphorus as a promoter in silica catalyst to the formation of formaldehyde was discussed on the basis of catalvst characterizations bv XPS, IR and TG methods.

The kinetics of oxidative coupling of mcthane over La2O3/BsaSO4 catalyst has been studied. 'The effects of internal and extenal diffusion were eliminated by means of reducing the pellet size of catalyst and incrcasing the linear velocity, respectively. The kinetic cquation at 680℃ was led to the follow The Iangmuir-Hinsthwood mechanism proposed0 is consistcnt with the kinetic cxopmcntal results.

The activity of SrCO3/BaSO)4 catalyst for the oxidativc coupling of methane（OCM） was studicd. The result revcals that SrCO3/BaSO)4 catalyst exhibits comparatively high activity The addition of ThO2 mcreases C2 yield and selectivity obviously and gives 18 2% C2 yield and 61. 3%, C2 sclectivity, The relation between activity and acid-base property of catalysts was studied by the techinique of TPD. 'The the phase composition of the catalysts was analyzed catalysts was analyzed by XRD and inferred the relation of structure with activity.
