MANUFACTURING METHOD OF ADSORPTION FILTER

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an adsorption filter which collectively conducts burning for a mesoporous inorganic material manufacturing process and burning for a honeycomb manufacturing process to reduce a production cost. SOLUTION: The manufacturing method of the adsorption filter carrying on it a mesoporous inorganic material whose pore sequence having a hexagonal structure having three-dimensional high regularity has; a process 1 in which a raw material is dissolved in a solvent to prepare a raw material mixture solution; a process 2 in which a precursor solution of a nanostructure is formed, the nanostructure having an inorganic/organic complex structure which contains a surfactant and being used as a mold in the pores of the mesoporous inorganic material; a process 3 in which the solvent in the precursor solution is volatilized and removed by a pressure-reduced foaming processing to gain a gel comprising the inorganic/organic nanostructure; a process 4 in which the gel comprising the inorganic/organic nanostructure is pulverized; a process 5 in which a filter base material is impregnated with slurry for impregnation which is prepared by mixing the pulverized gel of the nanostructure, a solvent and a binder; and a process 6 in which the filter base material impregnated with the slurry is subjected to burning processing.
