Process for the isomerization of unbranched hydrocarbons.

摘要

A process for the isomerization of unbranched hydrocarbons by separating a feed mixture containing different unbranched hydrocarbons (e.g. C5-C7 n-paraffins) into at least two fractions having different average molecular masses, introducing each fraction separately in order of increasing average molecular mass further downstream into a series of isomerization zones operated at isomerization conditions in the presence of hydrogen and an isomerization catalyst, and removing product from the furthest downstream zone.
