Abstract

A biomass fractionator and method are described for inputting ground biomass and outputting several vapor streams of bio-intermediate compounds along with syngas and biochar. In particular, a method for biomass fractioning, comprises dispensing biomass into thin sheets of ground biomass; subjecting the thin sheets to ramps of temperature; and selectively collecting various groups of compounds as they are released from the thin sheets.

Claims (12)

1. A method for biomass fractioning, comprising:

dispensing biomass into thin sheets of ground biomass;

subjecting the thin sheets to ramps of temperature using a plurality of biomass reaction compartments, wherein each biomass reaction compartment experiences an incrementally higher temperature than another compartment; and

selectively collecting various groups of compounds as they are released from the thin sheets.

2. The method of claim 1 , wherein the ramps of temperature are incremented over a range of times, pressures, or local working gas compositions.

3. A method for biomass fractioning, comprising:

chopping biomass, wherein a first biomass is produced;

loading the first biomass into an input hopper via one of a plurality of biomass reaction compartments;

dehydrating and pulverizing the first biomass;

heating the first biomass using a plurality of biomass reaction compartments, wherein each biomass reaction compartment experiences an incrementally higher temperature than another compartment; and

scraping residual carbon and biochar from one of the plurality of biomass reaction compartments into an exit hopper.

4. The method of claim 3 , wherein a next biomass reaction compartment is loaded with a second biomass while the first biomass is being dehydrated.
