Q1. A RTD experiment was performed on a reactor to collect the concentration time data at ambient conditions, Reaction is considered to be first order with a rate constant of (your roll no/l 600) min1 (e.g k=90600 for roll no 21BCH090 ). The observations are given in table (i) Construct the C(t),E(t), \& F(t) curves as a function of time (ii) Determine the fraction of material that has spent time between a. 2-15 min b. greater than 15 min (iii) Compute the value of three moments of RTD (iv) Find the conversion values using a. Segregation model b. Maximum mixedness model c. T-I-S Model - mention number of tanks clearly required d. Dispersion model - try closed-closed boundary condition-determine Peclet number All the solutions can be obtained cither by numerical integration f graphical integration Q2. t-Butyl alcohol is an important octane enhancer that is used to replace lead additives in gasoline. TBA was produced by liquid phase hydration of isobutene over Amberiyst-15 catalyst. The system is normally a multiphase mixture of hydrocarbon, water, solid catalysts. However, the use of co-solvents can achieve reasonable miscibility Consider the following mechanism, - I+SIS - W+SWS - I S+WS TBAS+S - TBA T TBA +S Derive a rate law assuming, (i) surface reaction is rate limiting (ii) desorption of TBA is rate limiting
