摘要： The invention relates to a composition for the purification of flue gas containing 1 to 99 wt. % of a powder of a sodium salt of carbonic acid and 1 to 99 wt. % of a powder of an absorptive material, wherein the powder of an absorptive material has a specific pore volume that is equal to or greater than 0.1 cm3/g. The invention also relates to a process for dry flue gas purification and the use of an absorptive material to improve the flowability and/or storability and/or HF absorptivity of a sodium salt of carbonic acid.

摘要： A method for the thermal treatment of mineral raw materials such as limestone or dolomite is shown and described, which includes at least the following steps of a. providing a mineral bulk material and a conductive material and b. placing the mineral bulk material and the conductive material into a kiln, generating an electromagnetic field inside the kiln, thermally treating the mineral bulk material in the kiln by means of electromagnetic excitation of the conductive material in the electromagnetic field, and removing the thermally treated mineral bulk material and the conductive material from the kiln. Using the method described, even large quantities of mineral bulk material can be efficiently converted.

摘要： The invention relates to a composition for the purification of flue gas containing 35 to 99 wt. % of a powder of an alkali metal salt of carbonic acid and 1 to 65 wt. % of a powder of an absorptive material, wherein the powder of an absorptive material has a specific pore volume that is equal to or greater than 0.1 cm3/g. The invention also relates to a process for dry flue gas purification and the use of an absorptive material to improve the flowability and/or storability and/or HF absorptivity of an alkali metal salt of carbonic acid.
