Theoretical-practical program

In the theoretical-practical classes, exercises to apply the concepts introduced in the theoretical classes will be solved, case studies will be discussed and some laboratory works will be proposed:
• Practical work 1: Production of biodiesel and study of some properties (2 classes).
• Practical work 2: Bioethanol production and its characterization (2 classes).

Evaluation Methodology
1 - Continuous evaluation

1.1 - Practical assessment (AP)= 0.4A + 0.3B + 0.3C
• A - Mandatory performance of all laboratory works.
• B - Attendance and participation in classes.
• C - Presentation of a work related to bioenergies.

1.2 - Theoretical assessment (TA): written test.

2 - Final evaluation: written test (TA).

3 - Final classification (CF) = 0.65AT + 0.35AP
