ABSTRACT:
In one embodiment the present invention provides for a regenerable sulfur remover that comprises a gaseous flow2, a first layer in line with the gaseous flow6, and a second layer8in line with the first layer. The first layer comprises a physical absorber of sulfur; the second layer comprises a pyrophoric material capable of being reduced by the gaseous flow. To regenerate the adsorbing layer, a blower22blows air first over the second layer, the air flow is heated by passing over the second layer, and then over the first layer. The heated air flow removes sulfur from the first layer, and the air flow is exhausted after removing sulfur from the first layer.
