摘要: Compositions are provided, derived from chemical treatment of carbonaceous fiber felt forms or other carbonaceous substrates, that exhibit both high efficiency and capacity for mercury capture from flue gases and the like. These compositions are superior to known compositions, particularly with regard to their performance under severely deactivating conditions. The compositions result from the pyrolysis of certain specific sulfur bearing compounds while in contact with activated carbon powders, activated carbon fibers, or with other carbonized forms. Precursor compounds to these novel mercury-binding compositions contain structural moieties that may be represented as: where X, Y are individual atoms or are functional groups consisting of several atoms, such that the atom bonding to sulfur is not hydrogen. X and Y can be linked in cyclic structures, either directly or through other atoms.

摘要: An improved filtration apparatus, filtering method and filtering material for capturing mercury and other pollutants in pollutant-laden fluid streams such as flue gases generated by process gas streams are disclosed. The improved filtration system may include two pollutant remediation layers, an upstream layer capable of filtering particulates and a downstream layer capable of adsorbing and/or catalyzing pollutants such as mercury, dioxin, furans, and NOx. The improved filtration system may be in the form of a particulate filter bag. The particulate filter bag may be configured for use in a reverse air filtration system with the upstream layer facing an internal volume of the bag. The upstream layer may include an ePTFE layer laminated to the upstream side of the upstream layer.
