Abstract
Production of acetylene by pyrolytic cracking of hydrocarbons following lr volumertric heating by: doping the feed stock with an absorbing gas such as ethylene to absorb laser radiation in a controlled manner: applying laser radiation in the form of a sheet with a thickness from about 5 to about 20 mm perpendicular to the flow direction of the feed stock; maintaining a reaction temperature around 1800.degree. to 200.degree. K by adjusting the energy output of the laser; and maintaining the temperature of the reaction chamber walls below 1000.degree. K.
Claims7
A method for pyrolytic production of acetylene which comprises:
- doping a hydrocarbon gas with an olefin to absorb laser radiation in a controlled manner;
- and
- irradiating said doped hydrocarbon gas with laser radiation to quickly raise said gas to a reaction temperature at which acetylene is produced.
