Objectives
AT THE END OF THE COURSE THE STUDENT WILL HAVE ACQUIRED THE FOLLOWING KNOWLEDGE AND SKILLS DECLINED ACCORDING TO THE MAIN DESCRIPTORS.

KNOWLEDGE AND UNDERSTANDING
THE STUDENT WILL KNOW THE CONFIGURATION OF REACTOR PLANTS WHICH BEHAVE FAR FROM IDEALITY FOR THE EFFECTS OF FLUID DYNAMICS, HETEROGENEITY OF THE REACTIVE SYSTEM, DECAY OF THE CATALYST AND PRESENCE OF MULTIPLE PHASES. THE STUDENT WILL UNDERSTANDING THE ASSUMPTIONS UNDERLYING THE DESIGN OF FIXED AND FLUIDIZED BED REACTORS.

APPLYING KNOWLEDGE AND UNDERSTANDING – ENGINEERING ANALYSIS
THE STUDENT WILL BE ABLE TO UNDERSTAND AND QUANTITATIVELY DESCRIBE REACTOR PLANTS WHICH BEHAVE FAR FROM IDEALITY FOR THE EFFECT OF FLUID DYNAMICS, HETEROGENEITY OF THE REACTIVE SYSTEM, DECAY OF THE CATALYST AND PRESENCE OF MULTIPLE PHASES.

APPLYING KNOWLEDGE AND UNDERSTANDING – ENGINEERING DESIGN
THE STUDENT WILL BE ABLE TO DESIGN REACTOR PLANTS WHICH BEHAVE FAR FROM IDEALITY FOR THE EFFECT OF FLUID DYNAMICS, HETEROGENEITY OF THE REACTIVE SYSTEM, DECAY OF THE CATALYST AND PRESENCE OF MULTIPLE PHASES.

MAKING JUDGEMENTS - ENGINEERING PRACTICE
THE STUDENT WILL KNOW HOW TO IDENTIFY THE NON-IDEAL CHARACTERISTICS OF A REACTOR AND IDENTIFY THE DESIGN PROCEDURES, KNOWING HOW TO IDENTIFY THE RELIABILITY LIMITS OF THE SOLUTIONS.

COMMUNICATION SKILLS – TRANSVERSAL SKILLS
THE STUDENT WILL BE ABLE TO REPORT ON TOPICS RELATED TO CHEMICAL REACTION ENGINEERING.

LEARNING SKILLS – TRANSVERSAL SKILLS
THE STUDENT WILL BE ABLE TO APPLY THE ACQUIRED KNOWLEDGE TO DIFFERENT INDUSTRIAL ENVIRONMENTS THAN THOSE REPORTED IN DURING THE COURSE, AND TO EXPAND THE COURSE TOPICS BY USING SOURCES DIFFERENT THAN THE PROPOSED ONES.
Prerequisites

Contents
DESIGN OF REACTORS WITH NON-IDEAL FLUID DYNAMICS (LEZ. 8; EX. 8)
DESIGN OF REACTORS AWAY FROM IDEAL CONDITIONS (BATCH, PERFECT MIXING AND TUBULAR) FOR THE FLUID DYNAMICS INVOLVED. CHARACTERIZATION OF REACTOR FLUID DYNAMICS THROUGH RESIDENCE TIMES. COMBINED EFFECTS ON THE REACTOR DESIGN OF THE REACTION ORDER AND THE NON-IDEALITY OF FLUID DYNAMICS. COMPARTMENT REACTOR MODELS AND DISPERSION MODELS. EFFECTS OF SEGREGATION IN TUBULAR REACTORS AND IN MIXED REACTORS. MAIN INVOLVED SINGLE-PHASE REACTOR SYSTEMS.

DESIGN OF HETEROGENEOUS REACTORS (LEZ. 6; EX. 2)
DESIGN OF REACTORS WITH REACTANTS AND SOLID PHASE CATALYSTS. METHODS OF CONTACT BETWEEN PHASES. DESIGN OF REACTORS CONTAINING POROUS CATALYSTS: DIFFERENTIAL, INTEGRAL, MIXED FLOW, WITH RECYCLE, DISCONTINUOUS. MAIN INVOLVED PLANTS OF HETEROGENEOUS CATALYTIC REACTORS.

DESIGN OF FIXED AND FLUIDIZED BED REACTORS (LEZ. 8; EX. 8)
DESIGN OF PACKED BED CATALYTIC REACTORS, ADIABATIC AND WITH HEAT EXCHANGE. CATALYTIC REACTOR DESIGN WITH SUSPENDED SOLIDS. FLUID BED REACTORS DESIGN - TWO-PHASE AND K-L MODELS. PRESENCE OF MULTIPLE REACTIONS. CIRCULATING BED REACTORS. HEAT EXCHANGE IN FLUIDIZED BED REACTORS. MAIN INVOLVED PLANTS OF FIXED BED AND FLUID BED REACTORS.

DESIGN OF OTHER CATALYTIC REACTORS (LEZ. 6; EX. 4)
DESIGN OF REACTORS USING DECAYING CATALYSTS. DESIGN OF SOLID-FLUID REACTORS: DISCONTINUOUS-DISCONTINUOUS, DISCONTINUOUS-CONTINUOUS PERFECTLY MIXED, DISCONTINUOUS-TUBULAR. INTERACTION BETWEEN DEACTIVATION AND CATALYST EFFICIENCY.

DESIGN OF THREE-PHASE REACTORS (LEZ. 6; EX. 4)
DESIGN OF THREE-PHASE REACTORS. KINETICS IN THREE PHASE REACTORS. DESIGN OF MIXING SYSTEMS FOR GAS-LIQUID REACTORS. MAIN THREE-PHASE REACTOR CONFIGURATIONS.

TOTAL HOURS 60 (LEZ. 34; EX. 26)
Teaching Methods
THE COURSE IS TAUGHT IN ITALIAN AND CONSISTS IN FRONT LESSONS (34H), AND CLASSROOM EXERCISES (26H) FOR A TOTAL AMOUNT OF 60 HOURS WHICH ARE WORTH 6 CREDITS. TEACHING INVOLVES LECTURES, INCLUDING THE USE OF MULTIMEDIA DEVICES FOR DISPLAYING CURRENT TECHNOLOGICAL SOLUTIONS, AND CLASSROOM PRACTICE. THE LECTURES PROVIDE THE THEORETICAL CONCEPTS AT THE BASIS OF THE TOPICS DISCUSSED. CLASSROOM PRACTICE HAS THE MAIN PURPOSE OF PUTTING IN PLACE CALCULATIONS FOR EQUIPMENT DESIGN.

ATTENDANCE OF LECTURES IS STRONGLY RECOMMENDED.
Verification of learning
THE EVALUATION OF THE ACHIEVEMENT OF THE EDUCATIONAL OBJECTIVES WILL TAKE PLACE THROUGH A WRITTEN EXAM AND AN ORAL INTERVIEW.

THE WRITTEN EXAM, IN WHICH THE CONSULTATION OF SOURCES IS ALLOWED, USUALLY LASTS 3 HOURS. THE TEST CONSISTS OF TWO DESIGN AND / OR VERIFICATION EXERCISES EACH CONSISTING OF A PART A AND A PART B. THE EXERCISES MAY REQUIRE THE USE OF A SPREADSHEET FOR THE SOLUTION. PARTS A CAN BE CARRIED OUT WITH THE APPLICATION OF STANDARD PROCEDURES AND THE CORRECT SOLUTION OF BOTH PARTS A ALLOWS THE ACHIEVEMENT OF SUFFICIENCY. MARKS HIGHER THAN SUFFICIENCY CAN BE ACHIEVED BY CARRYING OUT PARTS B OF THE EXERCISES WHICH, FOR THE SOLUTION, REQUIRE THE CORRECT APPLICATION OF SKILLS RELATED TO ENGINEERING PRACTICE. THE GRADUATION OF THE VOTE BEYOND SUFFICIENCY DEPENDS ON THE DEGREE OF COMPLETENESS OF THE SOLUTIONS PROPOSED FOR PARTS B.

WRITTEN MARKS REQUIRE TO BE CONFIRMED BY AN ORAL EXAM, IN WHICH THE FINAL EVALUATION CAN VARY FROM THE WRITTEN EXAM UP TO A MAXIMUM OF 6 POINTS.

THE ORAL EXAM LASTS BETWEEN 45 MINUTES AND 1 HOUR AND CONSISTS OF THREE QUESTIONS, ONE ON REACTORS WITH NON-IDEAL FLUID DYNAMICS, ONE ON REACTORS WITH SOLID CATALYSTS AND ONE ON THREE-PHASE REACTORS. REACHING THE MINIMUM THRESHOLD REQUIRES THE STUDENT TO DEMONSTRATE THAT HE IS ABLE TO CORRECTLY WRITE THE MATERIAL BALANCES IN THE VARIOUS REACTOR CONFIGURATIONS. EXCELLENCE IS ACHIEVED WITH A CORRECT WRITING AND WITH THE DEMONSTRATION OF COMPLETE MASTERY OF THE TOPICS DISCUSSED IN THE ORAL EXAM.
