Abstract: A catalyst is used in the reaction of brominating oxidation of methane. The catalyst is prepared by the following procedures: mixing at least one of the precursors selected from the compounds of Rh, Ru, Cu, Zn, Ag, Ce, V, W, Cd, Mo, Mn, Cr and La which can dissolve in water with the Si precursor, hydrolyzing, drying and sintering. Under the system of the catalyst, methane react with HBr, H 2 O and oxygen source(O 2 , air or oxygen-enriched air), and CH 3 Br and CH 2 Br 2 are produced finally. A catalyst is used in the reaction of dehydrobromination of brominated methane to prepare C 3 -C 13 hydrocarbon. The catalyst is prepared by loading the compounds of Zn or Mg on the molecular sieves such as HZSM-5, HY, Hb, 3A, 4A, 5A or 13X et al.. By using the catalyst, CH 3 Br and CH 2 Br 2 produced in the process of brominating of methane can react farther. At last C 3 to C 13 hydrocarbon and HBr are obtained and HBr can be used as cycling reaction medium.
