A model is developed for predicting temperature profiles in a gas cell containing an absorbing gas when irradiated by a CW laser beam with well-defined parameters. The model takes into account the explicit temperature dependence of heat capacities, thermal conductivities, molar absorptivities, and gas densities. The predicted transmittance of the laser beam as a function of incident power agrees with experimental values. The model is further used to predict rate parameters of a standard homogeneous pyrolysis reaction that is sensitized by the heated gas. The results provide insight into the comparison between the traditional thermal processes and CW laser sensitized pyrolysis.
