Report: U.S. highway diesel fuel’s sulfur content down 97 percent from 2006
This week marked a milestone for the United States’ transition to ultra-low sulfur diesel (ULSD) fuel as all highway diesel fuel hitting a 15 parts per-million (ppm) sulfur standard – a 97 percent reduction in sulfur content from diesel’s 2006 levels, according to the non-profit Diesel Technology Forum.
The December 1, 2010 deadline was mandated by the Environmental Protection Agency (EPA).
“It is quite a remarkable feat that refiners have been able to reduce the sulfur content in diesel fuel by 97 percent,” said Allen Schaeffer, the executive director of the Diesel Technology Forum. “The United States now officially has the cleanest on-road diesel fuel in the world,” he said.
“This new, ultra-clean fuel is extremely important because sulfur tends to hamper exhaust-control devices in diesel engines, like lead once impeded the catalytic converters on gasoline cars. Just as taking the lead out of gasoline in the 1970s enabled a new generation of emissions control technologies that have made gasoline vehicles over 95 percent cleaner, removing the sulfur from diesel help usher in a new generation of clean diesel technology,” Schaeffer.
