AI Technical Summary
Existing technologies cannot simultaneously produce high-quality activated carbon and high-modulus water glass, and the process is complex, with problems such as large amounts of activator and large amounts of waste liquid discharge.
After rice husk pretreatment, high-quality rice husk activated carbon and high-modulus sodium silicate are prepared by carbonization with reducing gas and activation with steam, combined with wet extraction of sodium silicate solution. The activation temperature and steam ratio are optimized, and the process flow is simplified.
This method enables the efficient preparation of high-quality rice husk activated carbon and high-modulus sodium silicate, reducing energy consumption, simplifying the process, improving product quality and production efficiency, and is suitable for industrial-scale promotion.
