Abstract: Processes and compositions are provided for decreasing emissions of mercury upon combustion of fuels such as coal. Various sorbent compositions are provided that contain components that reduce the level of mercury and/or sulfur emitted into the atmosphere upon burning of coal. In various embodiments, the sorbent compositions are added directly to the fuel before combustion; are added partially to the fuel before combustion and partially into the flue gas post combustion zone; or are added completely into the flue gas post combustion zone. In preferred embodiments, the sorbent compositions comprise a source of halogen and preferably a source of calcium. Among the halogens, iodine and bromine are preferred. In various embodiments, inorganic bromides make up a part of the sorbent compositions.

Abstract: A process for burning coal or other carbonaceous fuels captures sulfur and other undesirable compounds are captured and retained in non-reactive ceramic-like form after the combustion phase. The process involves addition of multiple element alkali powders and/or sorbents preferably containing oxidizing anions such as nitrates and nitrites, preferably based on calcium. In various embodiments, the remediation materials when applied in a complex powder and/or liquid containing multiple elements, result in higher sulfur capture than the materials would otherwise achieve on an individual basis. In a preferred embodiment, the sorbents contain elements that minimize or lower the melting point of the ash. This leads to lowered cohesiveness and toughness of the ash so that less ash builds up on the boiler and better heat transfer is obtained.

Abstract: Sulfur emissions from combustion of coal and other fuels are reduced by using sugar beet lime as a sorbent during the coal burning process. In various embodiments, the sugar beet lime is added onto the coal before combustion, along with the coal into the furnace, is injected directly into the fire coal, or is added into the flue gases downstream of the furnace. The relatively high calcium content of the sugar beet lime leads to efficient sulfur capture at suitably low treat levels. Excess ash is avoided in the process.
