A process for treating a light cracked naphtha to be used as an etherification feed stock is disclosed in which mercaptans, hydrogen sulfide and diolefins are removed simultaneously in a distillation column reactor (10) using a reduced nickel catalyst. The mercaptans and hydrogen sulfide are reacted with the diolefins to form sulfides which are higher boiling than that portion of the naphtha which is used as feed to the etherification unit. The higher boiling sulfides are removed as bottoms (8) along with any C6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process.

Procédé de traitement de naphta léger de craquage pour en faire le courant d'apport d'un processus d'éthérification, consistant à en extraire simultanément les mercaptans, l'acide sulfhydrique et les dioléfines dans un réacteur (10) à colonne de distillation au moyen d'un catalyseur au nickel réduit. Les mercaptans et l'acide sulfhydrique réagissent avec les dioléfines pour former des sulfures dont le point d'ébullition dépasse celui de la portion utilisée comme courant d'apport de l'unité d'éthérification. Lesdits sulfures sont ensuite extraits sous forme de résidus de distillation (8) avec tout C6 présent et tous les produits lourds. Toutes les dioléfines non converties en sulfures subissent une hydrogénation sélective donnant des mono-oléfines utilisées dans le processus d'éthérification.
