Thermal decomposition of 1,1-dichloroethene diluted in hydrogen.
The reaction of 1,1-dichloroethene in an excess hydrogen environment with a Cl/H ratio of 0.04 was investigated in an isothermal tubular reactor at a total pressure of 1 atm with residence time of 0.3-2.0 s between 575 and 900 degrees C. C(2)H(3)Cl and HCl are the primary reaction products from the decomposition of CH(2)CCl(2) while the formation of C(2)H(4), C(2)H(2), C(2)H(6), and CH(4) increases as reaction time or temperature increases. Modeling used a detailed chemical mechanism involving 59 species and 202 elementary reactions; the results were compared with experimental observations. Sensitivity analyses were also performed to rank the significance of each reaction in the mechanism. The optimal reaction condition for the C(2) hydrocarbons production from the dechlorination of CH(2)CCl(2) in H(2) environment was also determined.
