Abstract: Bio-oil is a renewable, environmentally-friendly energy source. The recovery of chemicals from it had attracted a lot of attentions and certain progress was also achieved over the past decades. In this paper, various methods for separation of chemicals from bio-oil were reviewed. Phenols can be extracted with organic solvents after alkalization-acidification treatment; acetic acid can be separated via reactive extraction; sugars can be recovered with organic solvents; and aldehydes can be separated by forming Schiff-base. The chemicals extracted from bio-oil can be used in agricultural, food or chemical industry, for instance, they are used as nitrogen slow-releasing organic fertilizer, flavoring additives, de-icer agent and phenolic resins. The main challenges for separations were summarized, and the future research directions were pointed out, too.

Key words: bio-oil, phenols, acetic, sugars, aldehydes, separation
