METHOD OF ACTIVATION OF SORBENT BASED ON METAL OXIDES Russian patent published in 1999 - IPC

FIELD: sorption techniques, in particular, cleaning of air mixtures from carbon monoxide; may be used in regeneration and activation of sorbents based on metal oxides. SUBSTANCE: method of activation of sorbent based on metal oxides for absorption of carbon monoxide includes treatment of sorbent in fluidized bed furnace at temperature of 120-320 C, pressure of 200-400 kgf/sq. m with gas-air mixture containing, vol.%: CO₂, 0.4-1.0; CO, not more 0.01; O₂, 16-22; nitrogen and inert gases with sorbent-gas-air mixture volumetric ratio of 1:(5000-9000), the balance. EFFECT: regeneration of initial activity of sorbents based on metal oxides with respect to carbon monoxide after their prolonged storage.
