Desulfurization at a glance. Desulfurization is the process of using hydrogen gas to reduce the sulfur content in hydrocarbons thus reducing the emissions of sulfur oxides which are responsible for acid rain. Countries across the globe have increasingly strict regulations in place to limit the sulfur content in fuels.
