METHOD FOR MAKING DOLOMITE POROUS, MANUFACTURING METHOD OF POROUS DOLOMITE MATERIAL, POROUS DOLOMITE MATERIAL OBTAINED BY THE MANUFACTURING METHOD AND UTILIZATION METHOD OF THE POROUS DOLOMITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for making dolomite porous enhancing adsorption performance by making porous with enhancing pore volume of dolomite without depending on difference of a composition due to production place of a dolomite ore which is a raw material and settings of burning conditions such as temperature, a manufacturing of a porous dolomite material, the porous dolomite material obtained by the manufacturing method and a utilization method of the porous dolomite material.SOLUTION: There is provided a method for making dolomite porous and high adsorption by burning so that the content of a retained CaMg(CO)phase in a dolomite burnt article analyzed using a Rietveld method by powder X-ray diffraction of the dolomite burnt article is 0.4≤x≤35.4 (mass%) and adjusting retained amount of the CaMg(CO)phase, and the porous dolomite material can be used for exhaust gas adsorption or virus inactivation.SELECTED DRAWING: None
