New approach plucks more sulfur from diesel fuel

An international industry-academic research team has reported a new approach to removing sulfur from diesel fuel that could improve vehicle performance and reduce the environmental impact of using fossil fuels. Gasoline and diesel contain residual amounts of natural organosulfur compounds that can foul catalytic converters and generate polluting sulfur dioxide. Refineries employ heterogeneous catalysts such as cobalt-doped molybdenum sulfide that use hydrogen at high temperature and pressure to strip out as much sulfur as possible . . .
