2 - Adsorption at the Gas-Solid Interface and Textural Characterization of Porous Materials
Physical and chemical adsorption. Adsorption equilibrium isotherms.
Porous solids; mechanisms of retention of gases.
Analysis of physical adsorption isotherms: B.E.T. method.
Standard isotherms. Analysis of isotherms using the -t and -ALFA methods.
Capillary condensation and evaporation. Application of the Kelvin equation.
Adsorption on microporous solids.
Characterization of porous materials (adsorbents and catalysts). Activated carbon.

Teaching methods and learning activities

The course consists of three 1-hour lectures per week and 1 hour of tutorials. The fundamentals and examples are presented in the lectures, while the tutorials are dedicated to problem solving.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

The students should not exceed the allowed number of absences (25 % of the scheduled tutorials) and must attend both tests (13/04 and 1/06), except in justified circumstances.

Calculation formula of final grade

The final classification (CF) will be the best of either
CF = 0.1 (CT1 + CT2) + 0.8 CEF
or
CF = CEF
where CT1 and CT2 are the classifications obtained in the tests and CEF is the final exam classification.

Special assessment (TE, DA, ...)

These students, and those that have already followed the course in the previous year, are excused from the tutorials.

Classification improvement

There will be another exam that the students can attend to improve their classification.
