    these techniques could yield 80-90% removal of inorganic sulfur. To remove sulfur that is organically bound in coal requires chemical or biological coal cleaning. Report results suggest that it is possible to remove up to 90% of either pyretic or organic sulfur from coal using oxidation agent at high temperature and pressure, and

  • Hydrodesulfurization - Wikipedia

    Hydrodesulfurization (HDS) is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide (SO 2) emissions that result from using those fuels .
