METHOD OF OBTAINING SOLID BIOFUEL FROM GRANULAR WOOD MATERIAL Russian patent published in 2010 - IPC C10L5/44 

FIELD: chemistry.

SUBSTANCE: method involves dropwise addition of diesel fuel to a pelleting press while pressing crushed wood wastes. The method of producing biofuel from wood wastes involves crushing, drying, mixing components and subsequent pressing, wherein the binder and component which reduces the load on the press matrix owing to increase in the slip coefficient between the material and cavities of the matrix is diesel fuel which is added in the following ratio, wt %: wood wastes 99.0-99.9; diesel fuel 0.1-1.

EFFECT: higher cost-effectiveness of the technological process without loss of quality characteristics of the obtained biofuel, improved water-repellent properties and higher combustion heat of the biofuel, lower ash content and high wear resistance of the press matrix.
