CATALYST SUPPORT WITH BASE OF SILICON CARBIDE WITH HIGH SPECIFIC SURFACE AREA IN GRANULATED FORM HAVING IMPROVED MECHANICAL CHARACTERISTICS

摘要

The invention concerns a catalyst support in granulated form, with a SiCβ base, of high specific surface area and having improved mechanical characteristics characterised in that its porosity comprises essentially pores ranging between 0.001 and 1 νm and in that it has a crystallinity defined by: a breadth at half height of the X-ray diffraction lines corresponding to the plane [2 2 0] of crystallites of SiCβ ranging between 0.15 and 0.60°, angle 2υ of Bragg's law; a two-dimensional peak height [1 0] corresponding to directions [1 0], over the peak integrated intensity of plane [2 2 0] ranging between 0.15 and 0.40.
