Thermocondensed lignocellulose material, and a method and an oven for obtaining it |
摘要 |
This material which has a hemi-cellulose content of less tha 2%, a benzopyrene content of less than 2 ug/kg and a calorific value which is about 20% greater than that of the starting material is obtained by isothermal treatment between 220 DEG C. and 280 DEG C. for a period of thirty minutes using crossed flows of treated material and of oxygen-free hot gases in an oven including stirring means (6,9) and a gas generator (1) with the gas being circulated by a fan (3).
