Abstract
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, and C-hydrocarbons. C-hydrocarbons are removed from the stabilizer overhead vapor stream to form a HCl and H-rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H-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.
