摘要 |
The invention relates to a method for producing a supported catalyst, consisting of at least 75 wt. % Al2O3, whose delta- or theta-modified fraction of Al2O3 is at least 1 % of the total Al2O3 fraction and which contains a rhenium compound and optionally a promoter as the active component (A). According to the invention: a) a modified support (T) is produced from a conventional support (T) consisting of at least 75 wt. % of Al2O3, to which a promoter is optionally applied, the delta- or theta-modified fraction of the Al2O3 being at least 1 % of the total Al2O3 fraction, by the calcination of the conventional support (T) at a temperature of between 750 and 1100 DEG C; b) a supported catalyst precursor is produced from the modified support (T) by the application of the active component comprising the rhenium compound (A) to the modified support (T); and c) the supported catalyst precursor is calcinated at a temperature of between 500 and 750 DEG C. |
