CH3021 CRE LAB


Objectives:

This laboratory course will reinforce the students’ understanding of basic concepts pertaining to analyze kinetics for complex reactions using differential and integral methods. Batch reactor will be employed to analyze rate kinetics for isothermal and exothermic reactions. The tracer dynamics in reactors will be studied using Residence Time Distribution. A few applications of chemical reactions involving electrochemistry, photocatalytic degradation, adsorption kinetics, oscillating kinetics, kinetics in biodiesel, kinetics for dye degradation using microwaves  and multiphase reactions will be studied.  The analysis will  include  various experiments with the objective of  sample preparation, measurement of concentration, prediction of kinetics and modeling of kinetics data. Learning outcomes:Students will a.    familiarize with suitable measurement techniques and devices to measure concentration and temperatureb.   learn to employ various methods to determine the kinetics of reactionsc. quantify the effect of non-ideality of flow in chemical reactorsd.         calculate the effects of mass transfer on chemical reactionse.     predict  errors in experimentation and compare experimental data with models
