Abstract
Homogeneous gas-phase pyrolysis of propane was performed by using continuous CO2 laser irradiation for bulk heating of the reaction mixture. Laser energy was absorbed by ethylene, the main product of propane dehydrogenation, and transferred to the reaction medium via collisional relaxation. A mechanism of propane dehydrogenation is suggested to describe the pyrolysis process. The mechanism involves autocatalysis by ethylene and includes propane–ethylene interaction with the formation of ethyl and propyl radicals.
