Abstract
A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.
