RTI's TReND process for deep desulfurization of naphtha
The U.S. Environmental Protection
Agency (EPA) Tier 2 regulations
limit the sulfur content of gasoline to 30 ppmw
by January 1, 2004. At the same time, the sulfur content
of the crude oil in the marketplace is steadily increasing.
These divergent trends in sulfur have generated a
renewed interest in new and improved desulfurization
technologies for fluid catalytic cracked (FCC) naphtha—
the chief contributor (>90%) of sulfur in gasoline.
