METHOD OF PRODUCING FUEL FROM MODIFIED FIBRE MATERIAL (VERSIONS) AND METHOD OF PACKING FIBRE COMPOSITION USED TO PRODUCE FUEL Russian patent published in 2011 - IPC C12P7/10 B02C19/00 

FIELD: chemistry.

SUBSTANCE: each of the versions of the method involves cutting a fibre source to obtain a first fibre material and passing the latter through a sieve to obtain a second fibre material which has relatively high specific surface area, relatively high porosity and relatively low apparent density. The second fibre material is then mixed with yeast and/or bacteria and/or an enzyme to obtain fuel. The second version of the method involves hydrolysis of the fibre material before adding yeast and/or bacteria and/or enzymes. The method of packing the fibre composition involves putting the composition obtained by mixing the fibre material which has been cut and passed through the sieve with bacteria and/or an enzyme into a packet made from gas-permeable material and removing gas from it.

EFFECT: invention enables to shorten time for producing fuel owing to that the fibre material has large surface area for interaction with yeast or bacteria or enzymes, which can be uniformly distributed in the entire volume of the fibre material.
