    摘要: A heat-insulating material is provided in which thermal conductivity is controlled not to increase and good insulation properties are held even in a high temperature range. The heat-insulating material is formed of a spinel porous sintered body having a porosity of 65 to 90 vol. % and represented by a chemical formula XAl2O4 (X=Zn, Fe, Mg, Ni, or Mn) which is arranged such that large pores having a diameter of greater than 1000 μm occupy 25 vol. % or less of the total pore volume, fine pores having a diameter of 0.45 μm or less occupy 5 to 40 vol. % of the volume of the pores having a diameter of 1000 μm or less, at least one pore-diameter distribution peak is within a range of 0.14 to 10 μm, and is formed of sintered particles having a calculated average particle diameter of 0.04 to 1 μm.

    摘要: The object of the invention is a method for dissolving carbon dioxide from flue or other gas and for the neutralization of the solution obtained. The gas, in which the partial pressure of carbon dioxide is at least 0.4 bar, is led to a dissolution process, where the major part of the carbon dioxide is dissolved into a flow of water. The aqueous solution of carbon dioxide thus obtained is neutralized by passing it through a material containing feldspar minerals, at which time the hydrogen ions of said solution are replaced by ions of alkali or alkaline earth metals, and the aluminum in said material is converted into aluminum compounds that can be separated and utilized.
