Abstract
Thermal stability of a halide-promoted, supported noble metal reforming catalyst is improved by employing a modified alumina support whose alumina precursor comprises at least about 75 weight percent boehmite, having an average crystallite diameter no greater than about 60 Angstroms. The thermal stability of the support is improved by the inclusion of a minor amount of silica, preferably added as an alkali-metal silicate to a mull of alumina prior to its extrusion and calcination with subsequent washing to remove the alkali metal.
