A process for the separation of close boiling compounds comprising distilling a hydrocarbon mixture of said compounds in the presence of a high boiling diluent liquid and a solid adsorbent. The high boiling diluent is withdrawn from the bottom of the distillation column and recycled to the column. The process is particularly suitable for the separation of straight-chain isomers from isomerate mixtures, the separation of benzene from hydrocarbon mixtures and the separation of paraffins from olefins.

Hydrocarbon separation

Process for the separation of close boiling isomeric compounds comprising distilling a dilute solution of isomers in a high boiling compound in the presence of a solid adsorbent. Multi and/or monobranched as well as cyclic isomers are withdrawn at the top of the distillation column, while straight chain and/or mono branched isomers are retained within the solid adsorbent. The diluent solution of the high boiling compound is withdrawn from the bottom of the distillation column and recycled, where it may be combined with the feed isomer mixture or recycled straight to the top of the adsorption column.
