Abstract:	A 1-dimensional mathematical model has been developed for a hybrid solar entrained-flow gasifier that includes the effects of both high intensity solar radiation (during peak sun) and oxygen blown gasification (during high cloud cover or at night). Calculations using this model predict that solar gasification of Illinois 6 coal during peak sun will result in similar coal conversions (~95%), higher H22 /CO ratios (1.5 cf 0.37) and lower COconcentrations of the syngas (2% cf 7% at the exit) relative to oxygen blown gasification. Due to these large differences in outlet composition, it is apparent that syngas storage is necessary for a coal to liquids plant with a hybrid solar/oxygen entrained-flow gasifier.
