Abstract: A process for the treatment of a hydrocarbon fraction having a boiling point range beginning above 200.degree. C. and obtained in the cracking of hydrocarbons, in which the polymeric component resulting from the cracking pyrolysis is removed and the remaining polymer-free hydrocarbon is subjected to hydrogenation under such reaction conditions that the product is high in monoaromatic components while the polyaromatics are removed therefrom.

Abstract: A method of and an apparatus for carrying out exothermic reactions in suspensions containing catalyst particles as well as a reaction participant and wherein the suspension is pumped to the reaction pressure and thereby fed to the reaction vessel. According to the invention, the suspension is preheated, before entering the reaction zone in the same pressurized vessel by direct heat exchange with reaction products from the reaction zone before the suspension is passed into the latter.
