Sulfur removal (or deep desulfurization) is a growing challenge for the petrochemical and energy industries because of the ever increasing need for clean fuels in commercial and industrial sectors, even for fuel cell applications. This need is has become amplified with declining supply of sweet feed stocks and the need for sulfur removal from reformed renewable fuels. Intramicron has developed highly regenerable sorbents and microfibrous entrapped sorbents for gas-phase sulfur removal and liquid-phase sulfur removal that operate over a wide range of process conditions.
