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.
Claims14
A system for producing a fuel product from a biomass, the system comprising:
- a carbonizing unit configured to perform pyrolysis of the biomass to produce a solid phase char and a tar-laden gas, the carbonizing unit comprising a gas outlet through which the tar-laden gas exits the carbonizing unit;
- a condensing unit configured to receive the tar-laden gas from the carbonizing unit, to produce a liquid phase tar, and to stratify the liquid phase tar into heavier liquid phase tar and lighter liquid phase tar, the condensing unit comprising a gas inlet through which the tar-laden gas enters the condensing unit;
- a gas connection unit for gas connection between the carbonizing unit and the condensing unit, the gas connection unit comprising a gas pipeline that is continuous from the gas outlet of the carbonizing unit to the gas inlet of the condensing unit;
- and
- a mixing unit configured to receive the solid phase char from the carbonizing unit and the heavier liquid phase tar from the condensing unit, the mixing unit operable to mix the solid phase char and the heavier liquid phase tar;
- a shaping unit configured to compact into pellets or briquettes a mixture of the solid phase char and the heavier liquid phase tar produced by the mixing unit, thereby producing the fuel product.
