Abstract
Activated carbon for removal of sulfur containing materials from fluids. The activated carbon has a high sulfur capacity and can be manufactured without the addition of a catalyst. Lignite is treated to provide an activated carbon with a high mesoporosity and total surface area. The starting material has a high ash content, such as greater than 10% by weight.
