Problem 18.4Problems : A gas containing A (2 mol/m3) is fed (1 m3/hr) to a plug flow reactor with recycle loop (0.02 m3 loop volume, 3kg of catalyst), and the output composition from the reactor system is measured (2 mol/m3). Find the rate equation for the decomposition of A for the following cases. Be sure to give the units of rA, CA, and k in your final expression.Question : Very large ricycle, A R , n= Penyelesaian :

Karena Very Large Ricycle maka, kita gunakan perhitungan Mixed Flow Reactor.

Maka,=

1= = k = CAO.V.XA 2 (1) (0,75) m3 W.CA 3 (0,5) kg.hrSehingga di dapat :

. CA0,5 -rA =1 m3 mol 0,5 kg.hr m1,5
