“…Biomass energy is an abundant resource all over the world. The transformation of biomass into hydrogen-rich gas provides a potentially competitive means for producing energy and chemicals from renewable sources . It has been demonstrated by Cox et al that high hydrogen yields can be achieved through an adequate reactor design and the control of gasification conditions.…”

The characteristics of biomass air-steam gasification in a fluidized bed for hydrogen-rich gas production are studied through a series of experiments. The gasifying agent, air, was supplied into the reactor from the lower part of the reactor, and steam was added into the reactor above the biomass feeding location. The effects of reactor temperature, steam-to-biomass ratio, equivalence ratio ER, and the biomass particle size on gas composition and hydrogen production are investigated. From the experimental results, it can be seen that the higher reactor temperature, the proper ER, proper steam-to-biomass ratio S/B, and smaller biomass particle size will contribute to more hydrogen production. The highest hydrogen yield, 71 g H 2 /kg biomass (wet basis), was achieved at a reactor temperature of 900 °C, ER of 0.22, and S/B of 2.70. It is shown that under proper operating parameters biomass air-steam gasification in a fluidized bed is one effective way for hydrogen-rich gas production.

With the use of dolomite in the fluidized-bed gasifier and the use of nickel-based catalysts in the fixed bed reactor downstream from the gasifier, the characteristics of hydrogen yield from biomass are investigated in the present study. Some calcined dolomite is placed initially in the gasifier with an amount of 120 g/(kg h -1 ) biomass. To replace the eroded and elutriated dolomite, calcined dolomite (0.3-0.45 mm) is continuously fed and its feeding rate is determined by preliminary test. The influence of the operating conditions in the catalytic reactor on the production of gases, especially H 2 , is studied over the temperature range of 650-850 °C, for weight hourly space velocity (WHSV) in the range of 2.68-10.72 h -1 . In the gaseous product, the average content of H 2 exceeds 50 vol %; C 2 content is lowered to below 1 vol %, and nearly half of CH 4 is converted after the catalytic reactor. Over the ranges of experimental conditions examined, the highest gas yield reaches 3.31 Nm 3 /kg biomass, wet basis; the maximum hydrogen yield reaches 130.28 g H 2 /kg biomass, wet basis. This system shows a good performance over a lifetime test of 350 min.

“…One study has been carried out to incorporate recent experimental advances in addition to plausible changes in direction from previous analysis performed by NREL. An assessment of hydrogen production technologies concludes that biomass gasification is the most economical process for renewable hydrogen production (McKinley et al, 1990), whereas other analyses have shown that biomass gasification/shift conversion is economically unfavorable compared to natural gas-steam reforming, except for very low-cost biomass and potential environmental incentives. Pyrolysis with a valuable co-product approach yields hydrogen in the price range of 6-8 US $/GJ, which is promising application in the near-term .…”
