Answer to Question #236892 in Chemical Engineering for Jonny

Question

Suggest a method for increasing the conversion in the reactor so that the cumen production rate remains constant with reduced propylene feed consideration using. Ci=pi/RT, m=density×AV,

Answer 1

1. Conversion

Consider the general equation

aA + bB → cC + dD We will choose A as our basis of calculation.

A + ba B → ac C + da D

The basis of calculation is most always the limiting reactant. The conversion of species A in a reaction is equal to the number of moles of A reacted per mole of A fed.

For irreversible reactions, the maximum value of conversion, X, is that for complete conversion, i.e. X = 1.0.

For reversible reactions, the maximum value of conversion, X, is the equilibrium conversion, i.e. X = Xe.
