Patent ID: 11772072

Abstract:
Provided is a method of producing a porous molded body, the method including: the step of obtaining a molded body by molding a raw material that contains from 1 part by mass to 100 parts by mass of a bicarbonate compound (A) represented by AHCO3 (wherein, A represents Na or K) and from 0 parts by mass to 99 parts by mass of a compound (B) represented by BnX (wherein, B represents Na or K; X represents CO3, SO4, SiO3, F, Cl, or Br; and n represents an integer of 1 or 2 as determined by the valence of X) (provided that a total amount of (A) and (B) is 100 parts by mass); and the step of obtaining a porous molded body by performing a heat treatment of the molded body in a temperature range of from 100° C. to 500° C. and an atmosphere that contains water vapor in an amount of from 1.0 g/m3 to 750,000 g/m3 and thereby thermally decomposing not less than 90% by mass of the bicarbonate compound (A).
