Reactions Of Hydrogen With Chloroform And Trichloroethylene At High Temperatures, Burhan Mahmood
Reactions Of Hydrogen With Chloroform And Trichloroethylene At High Temperatures, Burhan Mahmood
Theses
The reactions of chloroform and trichloroethylene with hydrogen in the temperature range 550 to 1000°C were studied using tubular flow reactors of varying diameters. The residence time range was from 0.05 to 3.0 seconds.Two different concentrations of the chlorinated species were used, each with hydrogen in large excess. Flat temperature profiles (+/- 5°C) were achieved over 80 to 85 per cent of the 45 cm long reaction zone, with inlet gases preheated to about 400°C.
No chlorinated hydrocarbons, products or reactants were observed at /above 850°C. The major products at these temperatures were C2H2, C2 …
Conversion And Kinetics In The Reaction Of Chloroform With Water Vapor At High Temperatures, Chii-Guang Hwang
Conversion And Kinetics In The Reaction Of Chloroform With Water Vapor At High Temperatures, Chii-Guang Hwang
Theses
This is an experimental study on thermolytic reactions of chloroform with excess water vapor where kinetic parameters are determined and complete product analysis made at atmospheric pressure over a temperature range from 550to 1050°C. In this study, water vapor was introduced as a reactant to convert chlorine in chlorocarbons to stable HCl which is an easily neutralized end-product and thereby completely destroy chloroform. Substantial amounts of thermodynamically stable species: HCl, CO, CO2, C(s) etc. were observed as products.
The reaction was studied in a 46cm tubular flow reactor mounted in a furnace that had three independently temperature-controlled heating …
