摘要:

The by-products of biochar and bio-oil have a highly potential to be used for gas cleaning in biomass pyrolysis or gasification. On one hand, tar in producer gas is removed by physical treatment, such as oil absorption and char adsorption; on the other hand, tar is removed by chemical treatment, such as catalytic reforming by the functionalized char. This report will deliver our research works on gas cleanup (especially for tar removal) by using bio-char, bio-oil, and low-viscosity tar. In general, bio-char can effectively adsorb the light tar (e.g., VOCs), while bio-oil is more beneficial for absorption of the heavy tar. Additionally, catalytic conversion is considered as one of the promising alternatives for tar removal, because it converts tar to the additional syngas products. Bio-char can be used as a catalyst with fair performance in tar conversion. Noteworthy, the spent char catalysts can be gasified to recover energy without the requirement of frequent regeneration after deactivation. Furthermore, the high-performance char catalysts will be urgently developed to deal with contaminants including NH3, H2S and tar in syngas from the real biomass pyrolysis/gasification processes.
