New KOSi method for ultra-deep desulfurization of fuels to ~ 2ppm S

New KOSi method for ultra-deep desulfurization of fuels to ~ 2ppm S 28 February 2017 Scientists led by a team at Caltech and BP, and in collaboration with researchers at UCLA, ETH Zürich, and China’s Nanjing University, have developed a new method for potentially removing nearly all sulfur compounds (down to ~2 ppm) from gas and diesel fuel. The method uses Earth-abundant materials (potassium (K), oxygen (O), and silicon (Si)—hence its name, “KOSi”) and operates under mild conditions. Sulfur compounds in fuels such as gasoline and diesel create air pollution when the fuel is burned. To address that challenge, large-scale hydrodesulfurization (HDS) at refineries remove the majority of sulfur from fuel down to a government-mandated level. The new technique, however, has the potential to reduce sulfur down to a fraction of that amount, which would further reduce air pollution...
