Pressure Swing Adsorption refers to the process of purification of Hydrogen gas which is manufactured in a plant like rfinery. Hydrogen which is formed as a by-product in process like Reforming is also used as a raw material within the refinery process like Hydrotreating and Isomerization. So it has to be made impurities free for use. So Hydrogen is purified by the process known as pressure swing adsorption in which impurities are adsorbed on the surface and Hydrogen becomes clean.

How do you separate hydrogen from mixture of hydrogen and carbon monoxide?
Hydrogen can be separated from a mixture of hydrogen and carbon monoxide using techniques such as pressure swing adsorption or membrane separation. In pressure swing adsorption, the components are separated based on their ability to be adsorbed onto a solid surface under different pressures. Membrane separation exploits the difference in size and permeability of the molecules to pass through a membrane.

Does chemical adsorption have a high adsorption enthalpy?
no
Does physical adsorption have a low adsorption enthalpy?
Yes, physical adsorption typically has a low adsorption enthalpy due to weak van der Waals forces between the adsorbate and adsorbent. These interactions are reversible and non-specific, leading to lower enthalpies compared to chemical adsorption.
Is the adsorption capacity depend upon porosity of adsorbent?
Yes, the adsorption capacity of an adsorbent is influenced by its porosity. A higher porosity provides more surface area for adsorption to occur, resulting in a greater adsorption capacity. Therefore, materials with higher porosity generally exhibit higher adsorption capabilities.
Why physical adsorption is reversible process?
adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place

What is adsorption site?
An adsorption site is a location on a surface where molecules or particles can adhere or bind due to attractive forces. It is where adsorption occurs, where a substance accumulates on the surface of another material. Adsorption sites are important in processes like catalysis, gas separation, and water treatment.
Where are the gases that make up the solution we breathe separated?
An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.The most common method for air separation is cryogenic distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.Other methods such as Membrane, pressure swing adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA), are commercially used to separate a single component from ordinary air.
