Abstract: In one aspect, a gasification system for use with low rank fuel is provided The system includes a pyrolysis unit positioned to receive a feed of low rank fuel, the pyrolysis unit being configured to pyrolyze the low rank fuel to produce pyrolysis gas and fixed carbon. The system also includes a gasifier configured to produce a syngas stream using the received fixed carbon, a cooler configured to receive and cool the syngas stream, and a first conduit coupled between the cooler and the pyrolysis unit. The first conduit is configured to recycle at least a portion of the syngas stream to the pyrolysis unit such that the recycled syngas stream is mixed with the pyrolysis gas to produce a hydrocarbon-rich syngas stream containing gasification by-products. The system also includes a by-product recovery system coupled to the pyrolysis unit for removing the gasification by-products from the hydrocarbon-rich syngas stream.

Abstract: A system includes a grinder, a storage unit, and an organic compound production unit. The grinder is configured to produce a fuel slurry from a solid fuel, a liquid, and an organic compound that is miscible with the liquid. The storage unit is configured to supply the organic compound to the grinder. The organic compound production unit is configured to receive a portion of syngas generated by a gasifier to generate the organic compound for supply to the storage unit.
