Latest Patents
Hantzer holds a patent for a process for the production of silicon carbide with a large specific surface area. This invention focuses on creating fine grains of silicon carbide formed by an agglomerate of submicronic grains. The specific surface area of these grains is at least 100 m²·g⁻¹, making them suitable as carriers for catalysts in high-temperature catalytic reactions, which can reach up to 1000°C. The process involves generating vapors of silicon monoxide (SiO) by heating a mixture of SiO₂ and Si at temperatures between 1100°C and 1400°C, under specific pressure conditions. In a second reaction zone, these SiO vapors are then contacted with reactive carbon, which has a specific surface area of at least 200 m²·g⁻¹.
