Classification: CPC C  Y | IPC C

Claim 3:
4. A process for producing a biocarbon composition, said process comprising:
(a) pyrolyzing a first biomass-containing feedstock to generate a low-fixed-carbon material and a first pyrolysis off-gas, wherein said low-fixed-carbon material has a first fixed-carbon concentration from about 10 wt % to about 55 wt % fixed carbon on an ab solute basis;
(b) separately from step (a), pyrolyzing a second biomass-containing feedstock to generate a high-fixed-carbon material and a second pyrolysis off-gas, wherein said high-fixed-carbon material has a second fixed-carbon concentration from about 50 wt % to about 100 wt % fixed carbon on an absolute basis, and wherein said second fixed-carbon concentration is higher than said first fixed-carbon concentration;
(c) blending at least a portion of said low-fixed-carbon material with at least a portion of said high-fixed-carbon material, thereby generating an intermediate material;
(d) optionally, blending one or more additives into said intermediate material;
(e) optionally, drying said intermediate material; and
(f) recovering a biocarbon composition containing said intermediate material or a thermally treated form thereof;
wherein said low-fixed-carbon material is in the form of particulates in a continuous phase of said high-fixed-carbon material.
