Straw Black Liquor Steam Reforming in a Fluidized Bed Reactor. Effect of Temperature and Bed Substitution at Pilot Scale

“…For fluidized bed reactors at laboratory scale, defluidization is so severe that the operation of the reactor becomes impossible. The same problem has been observed in Kraft BL fluidized-bed air-blown gasification at bench scale. , A high steam/biomass ratio is beneficial because it increases the hydrogen content and diminishes the tar content; however, on the other hand, the LHV of the dry gas is also diminished as the CO 2 content increases and the CO and hydrocarbon content decreases because of the water gas shift and steam cracking reactions.…”
