Abstract

Ultraviolet laser initiated chain reactions are described. Preliminary laser photochemistry economics, laser power, and stability requirements for large scale chemical synthesis employing chain reactions is reported. A two step laser scheme for converting methane to ethylene with chlorine as an intermediate is proposed. Photochlorination of methane has been studied at 248 nm and 308 nm laser wavelengths as a function of pulse energy and temperature. KrF laser (248 nm) excitation gives a factor of 3 higher quantum yield than XeCl laser (308 nm) excitation. At 200°C using KrF laser, auantum yield of 27,000 was observed.
