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 overhead vapor stream that comprises HCl, H2, and C6-hydrocarbons. C6-hydrocarbons are removed from at least a portion of the stabilizer overhead vapor stream to form a HCl and H2-rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H2-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.
