Abstract

A method for the preparation of acetylene comprises, in combination, a first stage for thermally cracking liquid hydrocarbons which consist mainly of saturated hydrocarbons having boiling-points in the range of 175 DEG to 350 DEG C. to produce a gas which is rich in olefine content by passing the hydrocarbons through a reaction chamber filled with a catalyst from the group of copper, nickel, chromium, and nickel-chrome-steel, which is heated to 700-900 DEG C. under a reduced pressure not above 300 mms. mercury, an intermediate stage for diluting the gas produced in the first stage by mixing it with 3-7 times its volume of a diluent gas, and a second stage in which the diluted gas of the first stage is passed through a second reaction chamber filled with a catalyst selected from the group consisting of molybdenum, tungsten, nickel, and nickel-chrome-steel, and heated to a temperature of 1000-1200 DEG C. under a reduced pressure not above 300 mm. of mercury to produce acetylene. The initial hydrocarbon may be petroleum or light oils such as n-hexane, cyclohexane, decomposed petroleum gases, coke oven gases or synthetic hydrocarbons. The diluent gas may be hydrogen, the residual gas after acetylene extraction, or steam. The initial cracking may be carried out in a pebble heater system, and the second cracking is preferably effected in a refractory furnace. The resultant acetylene may be purified by an extraction method employing dimethyl formamide as a solvent.
