Abstract

PURPOSE: To prepare acetylene useful as a raw material in chemical industry, in high yield, by irradiating methane with converged laser beam, thereby effecting the dielectric break of the methane.
CONSTITUTION: Methane gas is introduced from the gas reservoir 4 into the reactor 1, and irradiated with laser beam generated with a laser gun 2 and converged with the mirror 3. Methane is dielectrically broken by the laser beam into acetylene and hydrogen to obtain the objective acetylene in high (about 90%) yield. The dielectric breakage is a phenomenon of explosive plasma formation occured when the pressure of methane gas in the reactor 1 is higher than a specific level (e.g. 100 Torr) and the intensity of the laser beam at the focus is extremely high (e.g. 50MW).
