CW CO2 laser photosensitized (SF6) homogeneous pyrolysis of n-alkanes (C5-C7) affords almost twice higher yield of important ethylene compared to conventional pyrolysis in tubular reactors. No production of heavy pyrolytic oils, resins or coke and very small alteration of the pyrolytic distribution with the conversion are other advantages of the laser process that can be ascribed to the absence of in conventional reactors important surface reactions.
