METHOD OF COMPOSITE FIBROUS ADSORBENT PRODUCING Russian patent published in 2016 - IPC C08L97/00 D01F6/54 D01F8/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to carbonic adsorbents production. Described is method of composite fibrous adsorbent production, characterized by that initial components taken are hydrolyzed lignin and polyacrylonitrile, making their mixed at ratio of 80:20 by weight, this mixture is placed into pyrolysis reactor, performing its blowdown by nitrogen flow, after that, mixture is heated in pyrolysis reactor at rate of temperature raising of 15 deg.·min^-1 until mixture temperature of 800 °C, maintaining this temperature for 0.5 hours, stopped heating and performing cooling of carbonized fibers to room temperature under nitrogen at rate of its flow of 50 cm³·min^-1.

EFFECT: producing adsorbent based on wood processing wastes in large quantities, having higher heat resistance and strength.
