 Supercritical adsorption

Supercritical adsorption refers to the process of adsorbing molecules from a supercritical fluid onto a solid adsorbent. A supercritical fluid is a state of matter that shares properties of both gases and liquids. It occurs when a substance is above its critical temperature and critical pressure, allowing it to diffuse through solids like a gas while maintaining a higher density and solvating ability similar to that of a liquid.
