I have a problem to my design report. This report topic is acrolein production of partial oxidation. I cant material balance using below data. 100 kmol of C3H6 is feed to the reactor.
Please help me?
Reations
C3H6 + O2   C3H40 + H2O
C3H4O + 7/2 O2   3 CO2 + 2 H2O
C3H4O + 1/2 O2   C3H4O2
C3H6 + 9/2 O2   3 CO2 + 3 H2O

Fractional Conversion of C3H6 fed to the reactor : 67 %
Conversion of C3H6 to CO2 : 8.7 %
Yield of C3H6 to C3H4O :47 %
Selectivity of C3H6 to C3H4O2 : 5 kmol/kmol
