Pyrolysis And Oxidation Reaction Of 1,2, Dichloroethylene In Ar; Ar And Ch4; Ar, Ch4 And O2 Mixtures, Byung Ik Park

Theses

The thermal reaction of trans-1,2-dichloroethylene (DCEE) in methane and oxygen mixtures in Ar bath gas has been studied in 10.5 mm I.D. tubular flow quartz reactors at I atmosphere pressure, isothermal temperature between 575°C and 1000°C, and times of 0.3 to 2.0 seconds.

The thermal reaction of trans-1,2-dichloroethylene in the gas phase proceeds via unimolecular HCI elimination under the reaction condition of the present experiments. The chain branching C-Cl bond fission reaction is expected to become important at the higher temperature, competing With the HCI elimination.

The decay trans- 1,2- dichloroethylene, intermediates and final product distributions varied in the absence …

An Elementary Reaction Model For Thermal Decomposition Of Cf2cl2 In A H2 Atmosphere And Experimental Studies On Oxidation Of Ch3oh Plus Ch4 Under Fuel Rich, Stoichiometric And Fuel Lean Conditions, Cheng Guo

Theses

Pyrolysis of CF₂CL₂ in an atmosphere of H₂, has been studied in a tubular flow reactor, 723 to 873 K. Overall eaction conversion proceeds via loss of Cl with CHF₂CL formation, then loss of the second Cl atom and CH₂F₂ product. Initiation occurs by unimolecular Cl atom loss. Subsequent chain propagation steps rapidly generate active H atoms which abstract Cl atoms, but abstraction of fluo-rine atoms by atomic hydrogen is slow at the temperatures of this study.

A small mechanism, about 35 elementary reaction steps, and a thermodynamic data base …

I: Reaction Of Ch3c1 With H2 And Ch4 Under Oxidation And Pyrolysis Conditions Ii: Kinetic Analysis Of C2h6, C2h4, And C2h2 Reactions With Oh, O, H, And Cl, Qing-Rui Yu

Theses

Experimental and detailed modeling are presented for the high temperature combustion systems involving CH₃Cl/CH₄/O₂ and C₃3Cl/H₂/O₂ reactions. More important C2 species reaction rate constant are created. A mechanism incorporating 263 step elementary reactions and 76 stable compounds and active radicals is developed based on (1) fundamental thermochemical and Kinetic principles (2) Quantum Rice-Ramsperger-Kassel (QRRK) theory analysis (3) accurate thermodynamic Properties and thermochemical analysis (4) reliable experimental data to validate our model.

The study of Part II evaluates and analyzes theoretically the rate constants of C₂H₆, C …
