摘要:
The invention relates to a solid inorganic composition for reducing dioxins and furans, as well as heavy metals, in particular mercury, present in flue gases, to a method for preparing such a composition, and to the use thereof for reducing dioxins and furans as well as heavy metals, in particular mercury, present in flue gases, by contacting said flue gases with said solid inorganic composition.
摘要:
The invention relates to a solid mineral composition of heavy metals, in particular mercury, in flue gas, to a method for preparing such a solid mineral compound and to the use thereof for reducing heavy metals, in particular mercury, in flue gas, by placing the flue gas in contact with the solid mineral composition.
摘要:
The invention concerns a method for reducing heavy metals, in particular mercury, present in flue gases comprising a step which consists in contacting the flues gases with a sorbent solid matter in dry state wherein the sorbent solid matter is a non functionalized metal compound.
摘要:
The invention relates to a pulverulent lime composition comprising an alkali metal and having a specific surface BET which is equal to or larger than 25 m2/g and a total porous volume BJH of nitrogen desorption which is equal to or higher than 0,1 cm3/g. The invention also relates to a method for producing said composition, and to the use of the same for reducing the quantity of exhaust gas produced.
摘要:
The invention concerns an extrusion product containing hydrated lime, in the form of a calcined extruded product containing at least a binding agent capable of withstanding the extrusion product calcination temperature. Said product is prepared by dry process mixing of hydrated lime, at least said binding agent and a plasticising agent, gradually incorporating water in said mixture so as to obtain a paste capable of being extruded, extruding said paste into said extruded product, drying and calcining the dried extruded product at a calcination temperature higher than the plasticising degradation temperature and lower than the hydrated lime decomposition temperature.
