Nut shell Activated Carbon Kiln<\/h2>\n\n\n\n

\n

The fruit shell activated carbon kiln is a core thermal process equipment specifically designed to convert fruit shells (such as coconut shells, apricot shells, and walnut shells) into high-performance activated carbon. The process revolves around two key steps: carbonization and activation, ultimately producing an activated carbon product with a well-developed pore structure and strong adsorption properties.<\/p>\n\n\n\n

Core Process Steps
Raw Material Pretreatment
The fruit shells are screened and crushed to remove impurities and ensure a uniform particle size (usually within a specific mesh range), providing stable conditions for subsequent thermochemical reactions.<\/p>\n\n\n\n

Carbonization Stage
In an oxygen-deficient environment, the fruit shells undergo high-temperature pyrolysis (approximately 600-800\u00b0C). Volatile components (such as water and tar) are removed, and a preliminary carbon skeleton is formed, laying the foundation for the activation process.<\/p>\n\n\n\n

Activation Stage
Using high-temperature steam activation (the mainstream process), at temperatures of 800-1000\u00b0C, steam reacts with the carbon surface to form a large number of micropores, mesopores, and macropores, significantly increasing the specific surface area and adsorption capacity. Post-Processing
After crushing, screening, acid washing, or water washing, refined products are obtained in various particle sizes and purities to meet diverse application needs.<\/p>\n\n\n\n

Technical Advantages and Product Features of Fruit Shell Activated Carbon Kiln<\/a>.<\/p>\n\n\n\n

Fruit shell activated carbon kilns precisely control temperature, atmosphere, and reaction time, producing activated carbon with the following significant advantages:<\/p>\n\n\n\n

Key Product Features
Developed Pore Structure: Surface area can reach 1000-1500 m\u00b2\/g, with a well-defined micropore distribution and high adsorption capacity.
High Strength and Abrasion Resistance: High mechanical strength and washability make it suitable for repeated regeneration, reducing operating costs.
Wide Applicability: High adsorption capacity for pollutants in water, air, and organic solvents (such as chlorine, phenol, sulfur, and pesticide residues).

Nut shell Activated Carbon Kiln Key Technical<\/h2>\n\n\n\n


Temperature Control<\/strong>: 400-600\u00b0C for the carbonization stage and 800-1000\u00b0C for the activation stage, with an accuracy of \u00b15\u00b0C to ensure pore structure stability.
Atmosphere Control<\/strong>: Oxygen content monitoring and inert gas (nitrogen) supplementation are used to maintain a weakly oxidizing environment to avoid excessive ablation.
Raw Material Compatibility<\/strong>: A variety of wood-based materials, including sawdust, coconut shells, and fruit shells, can be processed. The moisture content of the raw materials should be controlled at 10%-15% to improve thermal efficiency.<\/p>\n\n\n\n
