CDP6-CB

    Isobutylene is catalytically oxidized to methacrolein, CO 2 , and CO. Data, in terms of three pseudo-first-order, parallel, competing reactions, follow:

where k 1 = A i exp (-Ei/RT), i = 1,2,3

   
A 1 = 2989 s -1
A 2= 9466 s -1
A 3= 11,127 s -1
E 1= 10.87 kcal/g mol
E 2= 15.11 kcal/g mol
E 3= 15.06 kcal/g mol
R =0.001987 kcal/g molmiddotK
   
    The reactor is a fluidized bed of catalyst particles. Use a CSTR model to calculate the expected conversions of i -butylene for all reactions under the following conditions:
