“…gasification and pyrolysis has already been developed [13,14,15]. Therefore, biomass gasification and pyrolysis-steam reforming for hydrogen production has drawn great interest, particularly using steam as the gasification agent and a suitable catalyst where the hydrogen yield can be significantly enhanced [16][17][18][19][20]. However, a challenge towards large scale commercialisation is tar formation in the product syngas and coke formation on the catalyst; the tar can block the pipework of downstream applications and the coke deposits on the surface of the reacted catalyst lead to deactivation [21].…”

“…In the last years biomass has been recognized as one of the major world renewable energy sources. Bio-oil derived from the fast pyrolysis of biomass or bio-ethanol can be converted via steam reforming into hydrogen or syngas, which can be further used in fuel cells or directed to synthesis of liquid fuels and valuable chemicals (Asadullah et al, 2002). For SOFC, an attractive option is direct internal reforming of bio-fuels on catalytically active anodes (Jamsak et al, 2007).…”

“…Steam can react with carbon monoxide to produce hydrogen and carbon dioxide. WGS reaction is the principle reaction in the steam gasification system (Chang et al, 2011;Rapagna et al, 2002;Asadullah et al, 2002). Hydrogen can also be produced from biomass by pyrolysis.…”

“…Tars may also act as poison for catalysts. Biomass chars are highly disordered carbonaceous materials with a short-range polycrystalline structure which consist of small aromatic structural units (Asadullah et al, 2002;Luo and Zhou, 2012;Duman et al, 2013aDuman et al, , 2014bNordgreen et al, 2011). Two main approaches employed for controlling the production of tar are, including treatments inside the gasifier (primary methods) and hot gas cleaning after the gasifier (secondary methods).…”
