Description
[0001] This application is a continuation of application Ser. No. 10 / 021,982, filed Nov. 28, 2001, now pending.BACKGROUND OF THE INVENTION
[0002] This invention relates to a sorbent composition, a process of making a sorbent composition, and a process of using a sorbent composition for the removal of sulfur from a hydrocarbon-containing fluid.
[0003] Hydrocarbon-containing fluids such as gasoline and diesel fuels typically contain a quantity of sulfur. High levels of sulfur in such automotive fuels is undesirable because oxides of sulfur present in automotive exhaust may irreversibly poison noble metal catalysts employed in automobile catalytic converters. Emissions from such poisoned catalytic converters may contain high levels of non-combusted hydrocarbons, oxides of nitrogen, and / or carbon monoxide, which, when catalyzed by sunlight, form ground level ozone, more commonly referred to as smog.
[0004] Much of the sulfur present in the final blend of most gasolines originates from a...
