Abstract
The present invention relates to a method for manufacturing a biofuel from a vegetable-based biomaterial by performing the manufacture in an integrated manner, in such a way that the biomaterial is made finer and dried with the aid of heat brought from a heat-releasing process, when the drying is finally performed after the finer making stage, optionally in such a way that drying is started already in connection with finer making. The invention also relates to a biofuel manufactured in this manner and the use of the fuel in question.
Claims18
A method for manufacturing a biofuel from a vegetable-based biomaterial, comprising the integrated steps of making the biomaterial finer in at least one stage by defibration and drying the biomaterial with the aid of heat brought from a heat-releasing process wherein:
- the drying starts in the grinder and is finalized after the finer making stage,
- the defibration is done to sliver mass, the slivers having a diameter of 0.1 to 0.3 mm and length of 1 to 5 mm, and
- the heat-releasing process is one that is intended specifically and only for producing the heat required for drying the biomaterial by combusting the biofuel.
A biofuel, manufactured from a vegetable-based biomaterial, wherein the biofuel is manufactured in an integrated manner comprising the steps of;
- making the biomaterial finer in at least one stage of integrated defibration and drying with the aid of heat from a heat-releasing process wherein:
- the drying starts in the grinder and is finalized after the finer making stage,
- the defibration is done to sliver mass, the slivers having a diameter of 0.1 to 0.3 mm and length of 1 to 5 mm, and
- the heat-releasing process is one that is intended specifically and only for producing the heat required for drying the biomaterial by combusting the biofuel.
A method for manufacturing a liquid biofuel from a vegetable-based biomaterial, comprising the integrated steps of making the biomaterial finer in at least one stage by defibration and drying the biomaterial with the aid of heat brought from a heat-releasing process wherein:
- the drying starts in the grinder and is finalized after the finer making stage,
- the defibration is done to sliver mass, the slivers having a diameter of 0.1 to 0.3 mm and length of 1 to 5 mm,
- the heat-releasing process is one that is intended specifically and only for producing the heat required for drying the biomaterial by combustion, and
- liquid biofuel is manufactured from the biomaterial that has been made finer and dried.
