FE-DOPED SILICA CATALYST

摘要

The invention relates to a catalyst, in particular for the partial oxidation of methane or natural gas to formaldehyde and/or methanol in the tange of 550 - 800 DEG C with oxygen or air, comprising a silica carrier having a BET-surface area of about 50 to 800 m<2>/g, a pore volume of about 0.01 to 2 cm<3>/g, a silanol group content of alkaline, alkaline earth and titania impurities of less than about 1.0 weight % and a content of alumina of about 0 to 1 weight % and an iron loading, expressed as Fe2O3, in the range of about 0.01 to 5 weight %, wherein the Fe-loading is about 0.01 to 10 Fe-atoms/nm<2> and the iron present as isolated Fe<2+>/<3+>-ions is higher than 10 weight %. The invention also relates to a method for preparing such catalyst and its use.
