Chemical and Biochemical Engineering
5.5 ECTS; 3º Ano, 1º Semestre, 30,0 T + 30,0 P



Development of skills in chemical kinetics studies and in analysis and design of isothermal ideal chemical reactors using mass balances, and development of skills in the analysis of real reactors through the residence time distribution theory.

1. Stoichiometry and kinetics of reactions
1.1. Quantitative parameters of the evolution of a reaction. Chemical kinetics
1.2 Collection and analysis of kinetic data. Methods for determining the kinetics of a reaction. Integral and differential methods. Method of reactant in excess.
2. Models of ideal reactors - mass balances.
2.1. Batch Reactors. Retention time and downtime.
2.2. Continuous Stirred Reactors.
2.3. Tubular reactors.
3. Real Reactors: Residence Time Distribution Theory - DTR.
3.1. Key features of the DTR functions and its experimental determination. Impulse and step inputs.
3.2. Modeling nonideal flow reactors through the DTR - Total segregation model, Maximum mixedness model, Dispersion model and Tanks In Series Model
3.3. Spreadsheet usage for RTD Theory application.

In laboratory classes, experimental work related to the determination of the kinetics reaction and to the residence time distribution theory will be conducted , using a tubular reactor and a CSTR type reactor at laboratory scale.
