Latest Patents

One of his latest patents is a cutting-edge membrane separation process aimed at sulfur reduction. This method allows for the efficient removal of sulfur species from naphtha feeds, specifically from FCC light cat naphtha, without compromising the yield of valuable olefins. The process employs a specialized membrane that exhibits excellent flux and selectivity, effectively distinguishing between sulfur-deficient retentate and sulfur-enriched permeate fractions. By implementing pervaporation conditions, this technology ensures that the sulfur-deficient fractions can be directly utilized in the gasoline pool, while the sulfur-enriched fractions undergo further treatment through conventional sulfur removal methods, such as hydrotreating. This invention is pivotal in delivering high-quality naphtha products that boast reduced sulfur content and enhanced olefin concentrations.
