CATALYST FOR SULFUR ISOLATION FROM GASES AND A METHOD OF ITS PREPARING Russian patent published in 1995 - IPC

Abstract RU 2046755 C1

FIELD: chemical technology. SUBSTANCE: for catalyst preparing ceramic cellular carrier is impregnated with solution containing a mixture of iron and copper or manganese salts followed by drying and calcination. Prepared catalyst has S 85-120 m2/g of the following composition, wt.-% Al2O3 13.4-21.6, SiO2 67.1-78.7, Fe2O3 0.5-5, Cu or Mn oxide 2.5-10. Ceramic cellular carrier is prepared using aerosilogel as a binder at concentration 40-60 wt. -% prepared by aerosil freezing at 0-(-25) C followed by defrosting and drying at 50-120 C. EFFECT: improved method of catalyst preparing. 3 cl, 3 tbl
