Abstract

Techniques, systems, apparatus and material are disclosed for generating renewable energy from biomass waste while sequestering carbon. In one aspect, a method performed by a reactor to dissociate raw biomass waste into a renewable source energy or a carbon byproduct or both includes receiving the raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction. Waste heat is recovered from an external heat source to heat the received raw biomass waste. The heated raw biomass waste is dissociated to produce the renewable fuel, carbon byproduct or both. The dissociating includes compacting the heated raw biomass waste, generating heat from an internal heat source, and applying the generated heat to the compacted biomass waste under pressure.

Claims

1. A method for processing biomass wastes to produce a renewable fuel or a carbon byproduct or both, the method comprising:

receiving a biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction;

recovering waste heat from an external heat source to heat the biomass waste, thereby removing air and moisture;

compacting the biomass waste;

advancing the compacted biomass waste in a dissociation zone;

creating a seal from at least some of the advanced compacted biomass to seal off the dissociation zone; and

applying heat to the advancing compacted biomass waste to create a pressure and temperature condition for dissociation of the biomass waste to produce the renewable fuel, the carbon byproduct, or both.

2. The method of claim 1, further comprising:

collecting the produced renewable fuel, carbon byproduct or both from the dissociation zone.

3. The method of claim 1, further comprising:

extracting other chemical species from the dissociation of the biomass in the dissociation zone.

4. The method of claim 3, wherein the extracted chemical species includes at least one of vaporous hydrocarbons, fuel alcohols, and gases such as ethane, methane, hydrogen, or oxides of carbon.

5. The method of claim 3, wherein the heat applied to the advancing compacted biomass waste is obtained via a countercurrent heat exchange from the extracted chemical species during cooling.

6. The method of claim 1, wherein recovering the waste heat comprises at least one of recovering heat rejected from an engine, or generating heat from a renewable energy generator including at least one of a wind energy generator, a solar energy generator, an energy generator from running water, or a geothermal energy generator.

7. The method of claim 1, wherein the renewable fuel comprises at least one of hydrocarbon, alcohol, ammonia, or hydrogen, and wherein the carbon byproduct comprises at least one of carbon dioxide, carbon monoxide, or carbon.

8. The method of claim 1, further comprising:

applying a catalyst to facilitate formation of the renewable energy comprising a hydrocarbon,

wherein the catalyst includes one or more of chromium, ceramics with rare earth constituents, a platinum metal group, nobleized nickel, and intermetallics of transition metals.
