FIELD: inorganic chemistry, chemical technology. ^ SUBSTANCE: invention proposes material showing the micro-mesoporous structure and a method for preparing material possessing acid centers with the desorption activation energy of ammonia 140-190 kJ/mole wherein their part in the total acidity value is less 0.5, and showing the developed regular porous structure with pores volume 0.45 cm3/g, not less, wherein part of micropores is 0.01-0.60, and part of mesopores is 0.10-0.85. Method involves suspending microporous crystalline silicates of the zeolite structure with the composition of anionic carcass T2O3*(10-1000)SiO2 wherein T means elements chosen from the group consisting of p-elements of the III group or d-elements of IV-VII groups of periodic system of elements, or their mixture in an alkaline solution up to achievement of the residual content of zeolite phase in suspension 1-60 wt.-%, addition of the surfactant silicate solution to suspension followed by addition of acid up to gel formation and hydrothermal treatment of gel and isolation of the end product. Invention provides preparing the material showing the crystalline structure of the parent silicate. ^ EFFECT: improved preparing method. ^ 6 cl, 2 tbl, 3 dwg, 14 ex
