AimsToggle Navigation

A. To know the principles of the kinetics of chemical reactions, both in homogeneous systems and in different heterogeneous systems, in the absence and presence of catalysts.

B. To know the basic reactors for obtaining kinetic data.

C. To understand and apply the methods that allow the establishment of kinetic equations and the determination of kinetic parameters.



At the end of the subject, the student should be able to develop works that require the following tasks/activities:

- Perform balances of matter in systems with chemical reaction.

- Calculate the conversion in batch and flowing systems.

- Establish the design equations for batch, continuous perfect mix and piston flow reactors.

- Develop reaction rate equations from mechanisms and experimental data.

- Apply differential and integral methods of data analysis.

- Maximize product selectivity in systems with multiple reactions.

- Understand the physical and chemical steps that occur in catalytic systems.

- Apply the reaction controlling steps and quantify the limitations of matter transfer in heterogeneous systems (catalytic and non-catalytic).

- To know the causes for the deactivation of solid catalysts and the possible strategies for their minimization.

MethodologyToggle Navigation

Types of face-to-face teaching activities and student work:

Lecture or theoretical class (30 face-to-face hours): The professor exposes the objectives and most relevant kinetic aspects of each topic. For a good assimilation of the concepts and their application, he provides information, bibliography and documentation for the development of the teaching. The student assimilates the concepts, takes notes and plans the preparation of the subject. In addition, a proactive attitude is expected in class, raising doubts and complementary issues and responding to questions posed by the teacher. This participation will be taken into account in the final evaluation.

Classroom practice - problems (20 classroom hours): The professor selects model works and exercises to illustrate the concepts corresponding to the subject. He/she supervises and supports the problem solving work developed by the students. The student solves selected problems or the proposed works. He/she presents the results on the blackboard or through written reports.

Seminars - classroom tutorials (10 classroom hours): The teacher solves doubts and raises questions to be discussed. Analyzes the student's progress and perseverance. Recommends methods of work in the subject. Proposes work to the group. Guides and moderates the discussion of the results. The student actively participates in this teaching task, raising doubts arising in the programmed tasks. In addition, he/she exposes and discusses the results of the assigned works/problems, orally or in writing, individually or in group, on the assigned works. The participation in the seminars will be part of your final grade.



Types of non face-to-face teaching activities and student work:

Work, at home or in the library, personal and sometimes in groups using the available resources (theoretical classes, practical classes, bibliographic resources). Assimilates the fundamental concepts of each topic. Solves the questions raised in practical classes and tutorials. Solves the questions posed in the computer platform.

Acquires the necessary knowledge for his/her training as a chemical engineer and applies it in a reasoned way to practical situations.

Searches in the library or in other sources, preferably in the recommended bibliography, the necessary information for the extension of the topics exposed in the theoretical classes and for the resolution of theoretical questions and/or problems. The student acquires skills and abilities in the treatment of bibliographic resources to complement and reinforce the knowledge, making an effort in the discrimination between what is basic and what is of secondary importance (capacity of synthesis and analysis).

Dedication: 90 hours, 6 hours/week, 1.2 hours/day.

Assessment systemsToggle Navigation

The percentages indicated in the previous section are average values. The application intervals are indicated below.

The ordinary evaluation of the course is carried out through the continuous evaluation system. In any case, students will have the right to be evaluated through the final evaluation system, in accordance with the provisions of the UPV/EHU Evaluation Regulations (BOPV, March 13, 2017), regardless of whether or not they have participated in the continuous evaluation system. The final evaluation will consist of the number of tests necessary to demonstrate the acquisition of the competences of the subject and will be carried out in the official examination calendar.

In the case of continuous evaluation, the final grade will be established by weighting the grades obtained throughout the course:

Performance of teaching activities and exercises in seminars and non face-to-face assignments: 60-40%.

Written tests to be developed: 40-60%.

For this subject, in both continuous and final evaluation cases, not attending the final test will involve that the final mark will be not presented.

Additional details about the characteristics of the tests and evaluation system can be found in the virtual platform of the course (http://www.egela.ehu.eus).
