Use extent of reaction method. Formaldehyde can be produced by oxidation of ethylene and the following reaction may occur.

C2H4   +   ½ O2 ® C2H4O

C2H4   +   3O2 ® 2CO2     + 2H2O

The product gas analysis shows 28.57% C2H4O, 11.43% CO2, 11.43% H2O, 22.86% C2H4 and 25.71 % O2. Calculate the % conversion of C2H4 and selectivity, C2H4O / CO2.

    Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 O2 (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 and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream components: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...

    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...

Problem 4: Ethylene oxide (C2Ha0), an intermediate in the production of plastics, is produced by the partial oxidation of ethylene (Reaction #1) C2H4+ O2 CH4O 25% 1. Reaction #2-the combustion of ethylene to form CO2 and H20-is an undesired side reaction: 2. C2H4+ O2 CO2 H20 (Note: This reaction is not balanced) Assume no other reactions occur-specifically that recycled ethylene oxide is not further oxidized. Pure oxygen (not air) is used in the...
