Abstract

Procedure for thermal cracking of hydrocarbons. In the procedure the hydrocarbons are heated to reaction temperature and conducted into a reaction zone, where the flow is upward from below. The reaction zone (17) is formed of a pressure vessel (14) of which the cross section increases in the direction upward from below, whereby is achieved a uniform retention time without any perforated intermediate bottoms or equivalent placed in the reaction vessel. The walls of the reaction zone (17) subtend with the central axis an angle ( beta ) of which the magnitude is between 2 and 15 degrees. [GB2133033A]
