WOOD PULP CARBONIZATION PROCESS Russian patent published in 2003 - IPC

Abstract RU 2210538 C1

FIELD: woodworking industry. SUBSTANCE: woodworking waste pulp is thermally treated in oxygen-depleted atmosphere in stationary wave antinode of ultra-high frequency field at input specific power at least 2 W/cu.cm. Oxygen-depleted atmosphere is created by flow of one or several non- combustion-sustaining gases at their intake at least 0.1 l/min. Those gases are selected from nitrogen, carbon dioxide, argon, helium, and other inert gases. EFFECT: enabled environmentally safe single-stage, continuous process. 2 cl, 6 ex
