METHOD OF PRODUCING CARBON FIBROUS ADSORBENT Russian patent published in 1995 - IPC

Abstract RU 2049168 C1

FIELD: medicine. SUBSTANCE: nonwoven fabric made of viscose fibers or fibers on the basis of grafted copolymer of acrylonitrile and viscose at their ratio 1:(1.5-2.3), length is 5 mm, not less, fastened by needle-break-through method, closeness pinhole is 80-160 per 1 cm2. Fabric is impregnated with inorganic compound solution and dried. Then carbonization is carried out at temperature above 600 C at the rate of temperature increment 6-50 C/min up to the content of volatile products 15-35% and carbonization is continued at the rate 150-900 C/min. EFFECT: improved method of adsorbent producing. 2 cl
