Abstract
ABSTRACT A detailed thermochemical kinetic model consisting of 165 reversible reactions has been developed to describe catalyzed polymerization of methane under adiabatic conditions. The model, an extension of that previously proposed (Weissman and Benson, 1984, 1989), was tested against available experimental data for CH3C1 pyrolysis in the absence and presence of CH4 in the temperature range 1260-1310 K (Weissman and Benson, 1984). Predictions of major product yields are reasonable although predictive inadequacies are discussed. Product distributions in the CH4/CI2 reaction were studied as a function of inlet/mixing temperature (To = 750-900 K), reactor pressure (PR = 1.0 —5.0 atmospheres) and CH4:C1, mole ratio (1.0-2.0). Product distribution is shown to be a strong function of inlet temperature and reactanl mole ratio. Choice of these parameters define the “window” of accessible reaction conditions experimentally available for useful product formation. Commercially attractive C2 yields (C2 H 2, C2H4),...
