The pyrolysis of ethane and propane has been performed in the presence of carbon vapor at temperatures between 2,000°K and 5,000°K. This high energy environment is obtained by an electric arc struck between two graphite electrodes. The quenched gases are analyzed by gas chromatography. The major reaction products are acetylene and hydrogen. C 2 H 2 yields are a function of the C/H 2 , ratio, the power input, the reaction temperature and the total pressure. Power levels between 10 and 50 kw. and gas flow rates of 1.5 to 20 liters per minute have been used. The electric arc process of hydrocarbon cracking is compared with conventional methods of acetylene production.
