1. Main categories of solid sorbents
1.1 Two types of solid sorption
Solid sorption is the process by which molecules of a fluid (gas or liquid), called a sorbent, attach themselves to the surface of a solid, called a sorbent. In refrigeration and heat pump applications, the sorbent is the refrigerant. By the surface of the solid, we mean the external and internal surfaces created by the network of pores and cavities inside the sorbent.
There are two types of sorption process: physical sorption and chemical sorption. In this article, we'll mainly be talking about physical sorption, in which case we'll refer to adsorption, adsorbate and adsorbent. But it also deals with chemical sorption, and refers to chemical reactions.
