STEAM REFORMING PROCESS AND APPARATUS

摘要

Various processes and systems are disclosed for converting carbonaceous materials into a product gas stream. For instance, the product gas stream ma y be endothermically converted to a gas through a steam reforming process. The present invention is directed to various methods and systems for increasing throughput and efficiency of the system. Further, the present invention is also directed to sulfur removal methods and systems from a gas stream. A thermo-chemical apparatus (10) is capable of endothermically converting a carbonaceous material into a product gas stream. Apparatus (10) includes a fluidized bed (14) which is indirectly heated by one or more combustion devices (12). Fluid bed apparatus (10) is provided with one or more material introduction ports (16) and also with port (28) near the bottom of the react or for introduction of a fluidization medium which maybe steam, a gas, evaporat ed liquids other than steam or a combination thereof.
