Abstract

A procedure for thermal cracking of hydrocarbons. In the procedure, the hydrocarbons are heated to reaction temperature and conducted into the reaction zone, where the flow is upward from below. The fluid/gas mixture is by the aid of a helix system (16, 17) or by nozzles set in tangential rotation in the pressure vessel (14), which constitutes the reaction zone (18), whereby a uniform delay time is obtained without any intermediate bottoms impeding cleaning operations.
