METHOD OF OBTAINING GEOPOLYMER WITH CONTROLLABLE POROSITY, OBTAINED GEOPOLYMER AND DIFFERENT VERSIONS OF ITS APPLICATION Russian patent published in 2014 - IPC C01B33/26 C04B38/04 

FIELD: chemistry.

SUBSTANCE: invention relates to field of geopolymers. Objects of claimed invention are: method of geopolymer obtaining, geopolymer, obtained by said method, catalytic substrate or substrate for separation of chemical compounds, application of geopolymer in field of catalysis and filtering. Method of geopolymer obtaining contains the following successive stages, at which characteristic of general porosity of obtained geopolymer is specified; value for, at least, one parameter, selected from the group, including total quantity of water and granulometric composition of optional silicate components, which makes it possible to obtain claimed characteristic of general porosity, is determined; said preliminarily defined value is selected. Method also contains stage of dissolving/polycondensation of silica-alumina raw material in activating solution, which, if necessary, can contain silicate components. Geopolymer has monomodal mesoporosity with 50% pores, which have available diameter, determined by mercury porosimetry, spread for less than 5 nm (narrow distribution of pore size) or has monomodal macroporosity with 50% pores, which have available diameter, spread for less than 10 nm (narrow distribution of pore size) or for from 10 to 50 nm (wider distribution of pore size).

EFFECT: method makes it possible to obtain geopolymers in form of monolithic materials, porosity of which can be regulated still at the stage of mixture composition preparation.
