Low Sulfur Gasoline

The Separation Science research team at SRI has developed a cost-effective process for making low-sulfur gasoline (<40 ppm). The S-containing compounds are absorbed from gasoline, using specific zeolites, which are regenerated through a displacement cycle with ammonia.

Advantage
SRI's process is much less expensive than existing methods for reducing sulfur. Because the process also avoids hydrotreating, octane-enhancing components in gasoline are not destroyed.

Opportunity
With the U.S. government mandating significantly lower legal sulfur levels in gasoline, there is a growing need for a less costly and less complex process for sulfur reduction. SRI's technology presents a strong licensing avenue for a petroleum or engineering company, including the opportunity for working in partnership with SRI during the project's development and marketing.
