In one embodiment the present invention provides for a regenerable sulfur
remover that comprises a gaseous flow 2, a first layer in line with the
gaseous flow 6, and a second layer 8 in 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 blower 22 blows 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.
