SYLLABUS/CONTENT

Introduction: Fundamentals e background of catalysis: Catalysts, thermodynamic equilibrium, reaction rate, activation energy and Arrhenius equation, industrial reactors. Industrial catalysts: Homogeneous and heterogeneous catalysts. Heterogeneous catalysts: redox catalysts, catalysts for gas and liquid phase oxidations, hydrogenation and dehydrogenation catalysts, acid-base catalysts, multifuctional catalysts. Examples of catalysis applied to the development of ecosustainable processes or in the pollutant control. Methods of catalysts preparation: Support and properties. Synthesis of supports and of bulk catalysts. Precipitation, sol-gel, hydrothermal synthesis, stabilization, shaping. Zeolite synthesis. Synthesis of Raney Catalysts. Scale-up of catalysts preparation. Preparation of supported catalysts, methods of deposition and support selection. Impregnation with and without interaction (incipient wetness, homogeneous precipitation, ion exchange, adsorption) Catalyst characterization: techniques of characterization: morphology and physical characteristics, bulk and surface characterizations, technological properties. Low temperature vapour adsorption and physi-adsorption, Hg intrusion porometry, microscopy, spectroscopic techniques, programmed temperature techniques (TPD, TPR, TPO, TG, DSC, DTA). Assessment of dispersed active sites by transmission electron microscopy (TEM) or chemi-sorption. Experimental procedures to assess the catalytic activity. Reaction regimes and mass transport regimes in heterogeneous catalysis. Laboratory activities and examples: Synthesis of mesoporous alumina and evaluation of its zero charge point. Preparation of a supported catalyst: impregnation kinetics and dispersion. Characterization by electron microscopy (SEM, TEM) and physi-adsorption. Analysis of gas-solid catalytic systems: reactors, experimental methods for limiting conditions. Experimental planning for kinetic measurements, material balances e data acquisition. TON assessment. Inter-phase and intra-particle gradients. Gas-liquid-solid catalytic systems. TOF and activation energy assessment.

EXAM DESCRIPTION

Oral + reports on the laboratory experiences

ASSESSMENT METHODS

The commission is composed of two components and one of them is the teacher of the course. THe duration of the examination is not less than 30 min. In this way the commission is able to verify the achievement of the learning outcomes. If the learning outcomes will be not achieved the student is invited to study again and better following some teacher suggestions and explanations.
