8) Ethylene oxide is produced by the catalytic oxidation of ethylene. C2Ha(g)+1/202(g) C2H4O(g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion in the reactor is 25% , and 0.70 mol of CaHeO is produced per mol of C2H4 consumed. A multiple- unit process is used to separate the products: C2H4 and O2 are recycled back to the reactor, C2H4O(g) is produced as a product (at...
