CA 2262387
The invention concerns a method for processing feedstock containing for the most part olefin hydrocarbons containing 4 carbon atoms per molecule, comprising isobutylene, and butylene-1 and butylenes-2 in a ratio substantially corresponding to thermal equilibrium. Said feedstock is processed in a distillation zone, associated with a hydroisomerisation reaction zone, in which hydroisomerisation of at least one part of the butylene-1 into butylenes-2 is carried out, said method being characterised in that said hydroisomerisation zone is at least partly external to the distillation zone.
L'invention concerne un procédé de traitement d'une charge comprenant en majeure partie des hydrocarbures oléfiniques comportant 4 atomes de carbone par molécule, dont de l'isobutène, ainsi que du butène-1 et des butènes-2 en rapport correspondant sensiblement à l'équilibre thermodynamique, tel que l'on traite ladite charge dans une zone de distillation, associée à une zone réactionnelle d'hydroisomérisation, dans laquelle on réalise l'hydroisomérisation d'au moins une partie du butine-1 en butènes-2, ledit procédé étant caractérisé en ce que ladite zone d'hydroisomérisation est au moins en partie externe à la zone de distillation.
