Abstract
A single pass method of production of an improved biocoal product according to which biomass is thermo-chemically broken down into its constituent components, the components are modified, and selected components are recombined to form a much more valuable fuel product which is more waterproof, more durable, and has a higher energy density than the original biomass. Other non-selected components may be used to provide energy to the biocoal production process.
Claims35
A process comprising:
- pyrolyzing a biomass to produce a solid phase char and a tar-laden gas;
- condensing the tar-laden gas to produce a liquid phase tar;
- mixing the liquid phase tar with the solid phase char;
- and
- between the condensing and the mixing, maintaining the tar at a temperature above a softening point of the tar.
2 more elements
A fuel product comprising:
- a mixture of a solid phase char and a tar,
- the mixture being produced by:
- pyrolyzing a biomass to produce the solid phase char and a tar-laden gas;
- condensing the tar-laden gas to produce the tar in a liquid phase;
- mixing the liquid phase tar with the solid phase char, and
- between the condensing and the mixing, maintaining the tar at a temperature above a softening point of the tar.
3 more elements
A system comprising:
- a carbonizer configured to perform pyrolysis;
- a condenser configured to receive a gas output from the carbonizer and to produce a liquid phase tar;
- and
- a mixing vessel configured to receive a solid phase char from the carbonizer and the liquid phase tar, the mixing vessel operable to mix the solid phase char and the liquid phase tar,
- wherein the system is configured to maintain the tar at a temperature above a softening point of the tar.
2 more elements
A fuel product comprising:
- a combination of a char component and a tar component,
- wherein:
- the char component has a fixed carbon content of at least 75% on a dry basis,
- the tar component has a softening point of at least 80° C., and
- the combination has a density of at least 830 kg/m3.
