Obiettivi dell'insegnamento

The goal of the course is to provide a rigorous treatment of a variety of subjects in chemical and catalytic reaction engineering and kinetics. This will include:

-complex chemical reaction mechanisms and kinetics
-principles of reactor design and analysis
-transport effects in multiphase reactive systems
-advanced reactor design and practical applications

On completion of the course, the student will be able to design/analyze a variety of complex reacting systems in both traditional and non-traditional areas of Chemical Engineering, from the derivation of the chemical and catalytic knetics to the design of the reactor..

Argomenti trattati

Introduction:
fundamentals of chemical reaction engineering and the concepts of chemical reactions and reactors.

Behavior of chemical reactions and elements of reaction kinetics:
reaction rates and kinetic constants. Temperature and pressure dependence of kinetic constants. Rate of an elementary step. Reaction affinity. Open sequence of elementary steps. Closed sequence of elementary steps: catalysis. Structure of reacting systems: consecutive reactions, simultaneous reactions, complex reactions. Pseudo steady state and rate determining step approximations. Surface reactions. Mechanism of catalytic and non-catalytic reactions. Experimental determination of kinetic data and rate data analysis and determination of kinetic parameters and rate equations.

Behavior of chemical reactors:
The fundamental mass, energy and momentum balance equations for chemical reactors. Ideal reactors: Classification and characteristics of ideal flow reactors; simple reaction characteristics, calculation, and optimization; variable temperature and variable molar reaction, adiabatic temperature rise and expansion factor; complex response characteristics, complex reaction rate, selectivity, and yield calculations. Batch and semi-batch reactors; Plug flow reactors; CSTR reactors.
Non-ideal reactors: Complex Flow Patterns, micro and macro mixing, and Residence Time Distribution (RTD) function, measurement of RTD and its properties; reactor diagnostics and troubleshooting. Modeling non-ideal reactors: semi-Empirical Models for Reactors with Complex Flow Patterns. Heterogeneous reactors: fixed bed catalytic reactors and transport processes with reactions catalyzed by solids and non-catalytic gas-solid reactions (1D pseudo-homogeneous model; 1D pseudo-homogeneous model with axial dispersion; 2D pseudo-homogeneous model; 1D heterogeneous model; 1D heterogeneous model with inter- and intra-phase temperature and concentration gradients; intra-phase limitations and evaluation of effective transport properties). Chemical regime, internal and external mass transfer regimes. Fluidized bed reactors (modes of fluidizations and stabilities, evaluation of transport properties; reactor models). Multiphase flow reactors, gas-liquid, liquid-liquid reaction systems. Bioreactors.

Practical session: an industrial showcase will be selected as the main topic of the practical session of the course aimed at the analysis and design of the reactor unit
