Effect of λ =308 nm laser radiation on pyrolysis of 1,2-dichloroethane

An experimental investigation was made of the physical conditions under which the effect of laser radiation on the pyrolysis of 1,2-dichloroethane was greatest. It was established that laser radiation could ensure high values of the pyrolysis efficiency (50–60%) at temperatures 150–200 °C less than those usually employed in purely thermal pyrolysis. It was established experimentally that pyrolysis produced intermediate products which absorbed strongly laser radiation. A study was made of the influence of diffusion processes on the degree of pyrolytic conversion. The experimental dependences were accounted for on the basis of a kinetic analysis.
