The process and system of the invention converts solid and liquid carbonaceous feedstock into electricity, steam, fuels, and carbon dioxide with minimal air emissions. Oxygen is partially consumed in a fuel cell then exhausted to a combustor of a Twin-Fluid Bed Steam Gasifier Unit (TFBSGU) where it is consumed in burning carbon contained in ash.

The stream is then cooled and compressed. The compressed gas passes through an acid gas removal system removing carbon dioxide and sulfur bearing compounds. Steam is added to the clean gas to prevent coking and the stream enters the anode space of the fuel cell.

Synthetic fuels are produced from synthesis gas in a four-stage reactor system with a single recycle loop providing the requisite thermal capacity to moderate the high heat release of the reactions and to provide the reactants and reaction environments for the efficient operation of the process. The first stage converts a portion of the synthesis gas to methanol, the second stage converts the methanol to dimethylether, the third stage converts the methanol and dimethylether to fuel and the fourth stage converts the high melting point component, durene, and other low volatility aromatic components such as tri- andtetra-methylbenzenes to high octane branched paraffins. The four-stage catalyst used for hydrotreating is resistant to CO poisoning.

The larger part of this gas stream is recycled to the inlet of the first stage and mixed with the fresh synthesis gas stream. Alternatively, the fresh synthetic gas stream is mixed with the product of the second stage.

The liquid fuel is sent for blending into fuel products, such as gasoline, jet fuel, or diesel, and the water stream can be sent, for example, to the synthesis gas producing plant for steam generation.
