Estimating the term…
In some variations, the disclosure provides a renewable biocarbon composition comprising from 50 wt % to 99 wt % total carbon, wherein the biocarbon composition is characterized by a base-acid ratio selected from 0.1 to 10, an iron-calcium ratio selected from 0.05 to 5, iron-plus-calcium parameter selected from 5 to 50 wt %, a slagging factor selected from 0.001 to 1, and/or a fouling factor or modified fouling factor selected from 0.1 to 10. Some variations provide a process comprising: providing a biomass feedstock; pyrolyzing the biomass feedstock to generate an intermediate biocarbon stream; washing or treating the intermediate biocarbon stream with an acid, a base, a salt, a metal, H2, H2O, CO, CO2, or a combination thereof, and/or introducing an additive in the process, to adjust a base-acid ratio or other compositional parameter; and recovering a biocarbon composition comprising from 50 wt % to 99 wt % total carbon and optimized for a compositional parameter.
A process for producing a biocarbon composition with an optimized base-acid ratio, the process comprising:
A process for producing a biocarbon composition with an optimized expanded base-acid ratio, the process comprising:
