In the pyrolysis, partial oxidation or electric arc cracking of hydrocarbons to form an acetylene-containing gas, the product gas is quenched with a liquid consisting of naphthalene and carbon black and optionally aromatic hydrocarbons introduced into the gas through a nozzle comprising a hollow cylinder open at one end and into which the quenching liquid is introduced tangentially. Preferably the pressure in the nozzle is one-tenth to one-half the pressure of the liquid entering the nozzle. Additional carbon-containing naphthalene may be injected through conical jets. The temperature of the quench fluid is preferably 160-250 DEG C. and it may contain 20-40% weight of carbon black.
