Abstract
Official abstract text for this publication.
Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of separating an isomerization effluent into a product stream that comprises branched paraffins and a stabilizer vapor stream that comprises HCl, H 2 , and C 6 -hydrocarbons. C 6 -hydrocarbons are removed from the stabilizer overhead vapor stream to form a HCl and H 2 -rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H 2 -rich stream to form a chloride-promoted isomerization catalyst. A paraffin feed stream is contacted with the chloride-promoted isomerization catalyst in the presence of hydrogen for isomerization of the paraffins.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for isomerization of paraffins, the method comprising the steps of: separating an isomerization effluent into a product stream that comprises branched and un-branched paraffins and a stabilizer vapor stream that comprises HCl, H 2 , and C 6 -hydrocarbons; separating the stabilizer vapor stream into a net gas vapor comprising HCl, H 2 , and C 5 -hydrocarbons and a liquid stream that comprises C 2 - and C 3 + hydrocarbon; separating the net gas…
