Title (EN) PROCESS FOR THE ALKYLATION OF BENZENE
(FR) PROCEDE D'ALKYLATION DU BENZENE
Abstract:
(EN) A process for the alkylation of benzene contained in a mixed refinery stream is disclosed wherein the refinery stream (2) is first subjected to hydrogenation (14) of higher olefins prior to alkylation (12) to the benzene with selected types and quantities of lower olefins (1). Streams containing sulfur compounds may be pretreated by hydrodesulfurization. All of the process steps are advantageously carried out in distillation column reactors (10) to take advantage of that mode operation.
(FR) L'invention porte sur un procédé d'alkylation du benzène contenue dans un courant mixte de raffinerie (2) lequel est tout d'abord soumis à l'hydrogénation (14) des oléfines supérieures avant alkylation du benzène par des types et quantités sélectionnés d'oléfines inférieures. Les courants contenant des composés sulfurés peuvent être prétraités par hydrodésulfurisation. Toutes les phases du processus se dérouleront de préférence dans des réacteurs à colonne de distillation (10) pour bénéficier des avantages de ce mode d'élaboration.
