Catalyst support in granular form with a SiCbeta crystallite base and a high specific surface area having improved mechanical characteristics. The porosity of the support is between 0.001 and 1 um in size and the crystallinity of the support is determined by:a full width at half maximum of diffraction X rays, corresponding to plane [2 2 0] of the SiCbeta crystallites, of between 0.15 and 0.60°, angle 2theta of Bragg's law; anda bidimensional peak height [1 0] corresponding to directions [1 0] normalized by the integrated intensity of the peak of plane [2 2 0] of between 0.15 and 0.40. |
