INORGANIC SPHEROGRANULATED POROUS SORBENT BASED ON ZIRCONIUM HYDRIDE AND METHODS OF ITS PRODUCTION Russian patent published in 1996 - IPC

Abstract RU 2064825 C1

FIELD: chemical industry. SUBSTANCE: spherogranulated sorbent is based on zirconium hydroxide of formula: (ZrO2)x(MzO)10x•nH2O with 0.9 0,9≅ x≅, 0.1 0,1≅ n≅ 10, M - Na, K, Li under Z = 2 or M - Ca, Mg under = 1. Sorbent is produced by electrolysis of zirconium chloride water solution with production of sol, its conversion into spherogel and drying. Produced granules crushing strength is no less MPa, pores volume of 0.1 - 0.6 cm3/g. Sorbent is used for purification of different solutions and gasses in stream in food-processing and chemical industries, in atomic power industry. EFFECT: improved quality of solutions and gasses in stream purification. 5 cl, 3 tbl
