Desulfurization (IMAGE)
Caption
The ability to reduce sulfur in fuels is an important step toward reducing emissions. However, extremely low levels can be difficult to achieve. Now, Caltech researchers have demonstrated an unorthodox approach that lowers sulfur content in diesel to about 2 ppm. The method uses Earth-abundant materials (potassium (K), oxygen (O), and silicon (Si) -- hence the name, 'KOSi') and operates under mild conditions.
