“…They are mainly products derived from coal liquefaction, coal tar, and petroleum, and also from biomass via pyrolysis as documented in recent reports. 1,2 Because of the mixture of oil containing phenols, it is necessary to separate phenols before further refining. The present industrial method to separate phenol compounds from oil mixtures is chemical extraction using aqueous alkaline solutions (such as aqueous NaOH solution) and then acidification of the extract by mineral acids (such as aqueous H 2 SO 4 solution) to recover the phenols.…”

“…According to many previous studies on the separation of phenolic compounds from bio‐oil (see Table ), several researchers used many ways to separate phenolic compounds from bio‐oil, including steam distillation and purification , liquid‐liquid extraction , modified adsorption resin separation , and basification‐acidification extraction , however, the purity and recovery efficiencies for the phenolic compounds from bio‐oil in this study are comparatively high. Due to the combination of column chromatography technology and the basification‐acidification process, the crude product containing the target phenolic compounds was further separated and high‐purity monophenols were obtained.…”

“…When combined with other technologies, the basification‐acidification process, which is a well‐known extraction method, has been widely used for separating phenolic compounds from bio‐oil. Fractions with high phenol contents have been separated from bio‐oil through basification with sodium hydroxide (NaOH) or Ca(OH) 2 and subsequent acidification with HCl. When using Ca(OH) 2 in the basification of bio‐oil, the phenolic compounds of the bio‐oil react with the calcium ions (Ca 2+ ) to generate precipitate, which greatly simplifies the separation of phenolic compounds .…”

“…Considering the mild condition, extraction and column chromatography has been employed to separate bio-oil. Table 1 summarizes the literatures which focused on the separation of bio-oil by extraction and column chromatography [2,7,8,[16][17][18][19][20][21][22][23][24][25][26]. Extraction is always used as bench-scale separation technique of bio-oil and has been widely investigated to produce phenols and sugars (such as levoglucosan and glycolaldehyde) from bio-oil as Table 1 lists.…”
