Generate & Play Hailuo AI video：Charcoal becomes 'active' after a process that increases its surface area and makes it more porous, allowing for better adsorption. Here are the main steps: 1. **Physical activation:** Coal is heated to high temperatures (600 to 900°C) in a controlled atmosphere, often in the presence of gases such as carbon dioxide or water vapor. This process creates a porous structure by removing volatile compounds. 2. **Chemical activation:** The coal is impregnated with chemical agents (usually phosphoric acid or basic solutions) before being heated. This breaks down organic materials, creating pores and increasing the surface area for adsorption. These processes transform charcoal into activated carbon, which has varied applications, from water filtration and air purification to medical treatment and cosmetics.
