High efficient production of hydrogen from crude bio-oil via an integrative process between gasification and current-enhanced catalytic steam reforming

Hydrogen production from catalytic reforming of the aqueous fraction of pyrolysis bio-oil with modified Ni–Al catalysts

“…Additionally, up to 60-75% of crude biomass can be converted to liquid bio-oil in practical applications, demonstrating its technical maturity [11]. Steam reforming of crude bio-oil [3,7,12], aqueous fraction [13] as well as model compounds [14][15][16] or a mixture of them [17] for hydrogen production has been widely investigated.…”

“…The use of fluidized beds has also been reported to attenuate coke deposition on catalysts [29]. A current-enhanced catalytic steam reforming method has been proposed which reported less coke formation compared with the normal reforming method [12]. Reforming temperature and steam to carbon ratio were also found to be essential factors for coke formation as well as quality of product gas [30,31].…”

Effect of Coal Ash on the Steam Reforming of Simulated Bio-oil for Hydrogen Production over Ni/γ-Al2O3

“…It has been revealed that catalytic activity is not promoted when quartz is introduced (Kan et al 2010;Ren et al 2014). At this time, for the selected coal ash (ZDA), the gaseous products were changed, which can be ascribed to the components in ZDA, such as Fe2O3, MgO, and CaO.…”

“…The coke deposition and/or metal sintering decreased the metal surface accessible to reactants (Bengaard et al 2002). The catalysts adopted in bio-oil reforming have been frequently reported to suffer rapid deactivation (less than 1 h (Kan et al 2010) or 6 h (Fu et al 2014)). Considering the large amounts of acetic acid and furfural in the bio oil compounds, the coke deposition and catalyst deactivation were reasonable.…”

High efficient conversion of CO2-rich bio-syngas to CO-rich bio-syngas using biomass char: a useful approach for production of bio-methanol from bio-oil

“…In our previous work, attention has been paid to produce bio-syngas and hydrogen from bio-oil Kan et al, 2010;Yuan et al, 2008). The present work aims to efficiently adjust CO 2 -rich bio-syngas into CO-rich bio-syngas by using biomass char.…”
