Abstract:
The aim of this work is to evaluate the performance of a reforming-unit for the treatment of syngas and char produced in an air gasifier. This approach represents an alternative option to produce hydrogen-rich syngas from air gasification. The reformer reactor was operated under a range of temperatures and at different steam flows and for each operating condition the changes and improvements in producer gas composition were measured. The results highlight that in the absence of char and steam no substantial changes are measured in the producer gas composition, while in the absence of char but with a steam flow or in the absence of steam but with a char-bed a maximum hydrogen concentration increase +31 % can be obtained at higher temperatures. On the other hand, the combined effect of char and steam significantly improves the hydrogen concentration of approx. +194 % at 800 °C with the highest steam flow tested. These results provide a guide for future optimization studies into the enhancement of gas quality in air gasification systems.
