<p>PCT No. PCT/NO93/00196 Sec. 371 Date Jun. 2, 1995 Sec. 102(e) Date Jun. 2, 1995 PCT Filed Dec. 21, 1993 PCT Pub. No. WO94/14899 PCT Pub. Date Jul. 7, 1994In a method for the production of carbon black and hydrogen by means of pyrolysis of hydrocarbons with a plasma torch (3) in a reaction chamber the pressure in the reaction chamber (1), the feed rate for the hydrogen plasma gas and hydrocarbons and the angle of the injection nozzles (2) in the reaction chamber (1) are adjusted in order to establish a reaction zone (5) in the chamber's central area with a location which determines the reaction enthalpy for decomposition of the hydrocarbons into hydrogen and carbon black in order to obtain a desired quality for the carbon part. The enthalpy value is adjusted in a range between 1 and 50 kWh/Nm3 and the temperature in the reaction zone is maintained between 1000 DEG C. and 4000 DEG C.</p> |
