Abstract
In one aspect, a gasification system for use with low rank fuel is provided. The system includes a first gasifier positioned to receive a feed of low rank fuel, the first gasifier being configured to gasify the low rank fuel to produce hydrocarbons and fixed carbon. The system also includes a second 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 first gasifier. The first conduit is configured to recycle at least a portion of the syngas stream to the first gasifier to facilitate heating low rank fuel within the first gasifier. The recycled syngas stream is mixed with the hydrocarbons to produce a hydrocarbon-rich syngas stream. The system also includes a second conduit coupled to the first gasifier for receiving the hydrocarbon-rich syngas stream.
