|Title:||METHOD FOR MANUFACTURING SHAPED BETA-SIC MESOPOROUS PRODUCTS AND PRODUCTS OBTAINED BY THIS METHOD|
Method for manufacturing a β-SiC shaped piece comprising mesopores with a diameter of between 6 nm and 100 nm representing a mesopore volume (determined by mercury intrusion porosimetry) greater 0.35 cm3/g, said method comprising the transformation of a mesoporous carbon preform with at least one silicon source into silicon carbide (β-SiC), said silicon source being able to be incorporated in said preform or contributed from outside, said carbon preform having mesopores with a diameter of between 6 nm and 100 nm with a mesopore volume greater than 0.35 cm3 per gram of carbon. This β-SiC mesoporous shaped piece can be used as a catalyst carrier for chemical reactions involving a liquid phase, and in particular for the Fischer-Tropsch reaction.
