Sulfur and Mercury Removal - Posted at 10:13 AM on May. 20, 2009 by ausetute
Hydrodesulfurization is a catalytic process that is used to remove sulfur from natural gas (methane) and refined petroleum products such as petrol (gasoline), deisel and jet fuels.

Scientists in the USA have developed a new material to improve the process of removing sulfur. The new material, cobalt-molybdenum-sulfur, a new class of chalcogels, is stable to air or water and can be used as a powder.

A similar material made of  cobalt, nickel, molybdenum and sulfur is a gel which is freeze dried, producing a sponge-like material with a vast surface area. This gel is capable of soaking up heavy metals, like mercury, from polluted water because the mercury binds with the sulfur. This gel can also remove carbon dioxide from hydrogen which could be useful in the development of hydrogen as a fuel.
