    摘要: Process for producing a supported catalyst which comprises at least 75% by weight of Al2O3, whose proportion of Al2O3 in the delta or theta modification is, based on the proportion of Al2O3, at least 1% and which comprises a rhenium compound and, if appropriate, a promoter as active component (A), which comprises a) converting a customary support (S) which comprises at least 75% by weight of Al2O3 and to which a promoter may, if appropriate, have been applied is converted into a modified support (S) whose proportion of Al2O3 in the delta or theta modification is, based on the proportion of Al2O3, at least 1% by calcining the customary support (S) at a temperature of from 750 to 1100°C., b) producing a supported catalyst precursor from the modified support (S) by applying the active component (A) comprising the rhenium compound to the modified support (S) and c) calcining the supported catalyst precursor at a temperature of from 500 to 750° C.
