A plug flow reactor (PFR) is designed and tested, and the products of ethylene (C_2H_4) ozonolysis reactions are investigated using a gas chromatography (GC). Fuel and oxidizer are supplied separately into this PFR assembly at low concentrations, such that the ozonolysis reactions are slow enough to be studied under room temperature and atmospheric pressure. Numerical simulations are conducted to assist the design of PFR and to determine the boundary conditions of this experiment. By changing the ozone (O_3) concentration in oxygen (O_2) stream, products of the C_2H_4 ozonolysis reactions are diagnosed to check any difference in the product components. Some important products of C_2H_4 ozonolysis reactions like H_2, CO_2 and H_2O are observed by GC. This PFR study is promising for a better understanding to the chemical kinetics of C_2H_4 ozonolysis reactions, which can improve the accuracy of numerical simulations including ozonolysis reactions.
