ABSTRACT:
A process for treating a light cracked naphtha to be used as an etherification or alkylation feedstock in which the mercaptans and diolefins are removed simultaneously in a distillation column reactor using a Pd catalyst. The mercaptans 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 or alkylation unit. H.sub.2 S reacts in the same manner as the mercaptans to for the sulfides and is similarly removed from streams. The higher boiling sulfides are removed as bottoms along with any C.sub.6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process. Certain C.sub.5 olefins, for example pentene-1 and 3-methyl butene-1 are isomerized during the process to more beneficial isomers.
