The bioaqueous phase generated during biomass conversion to biofuel and biochemicals, e.g., fast pyrolysis and ex situ catalytic pyrolysis, contains a large number of organics, leading to a high chemical oxygen demand (COD) for its treatment. In this study, we demonstrate its catalytic conversion to bioacetic acid solution and propose a recycling strategy thereof. We found that the diluted bioaqueous phase (e.g., C content <0.5 wt %) can be selectively (>90%) converted to acetic acid with nondetectable impurities in solution. The solution contains 1.3–1.5 wt % acetic acid and can be directly used for demineralization of biomass in the biorefineries. This recycling strategy enhances the sustainability of the biobased economy and sheds light on production of biobased acetic acid, which has been recognized as a smart drop-in chemical.

催化湿式空气氧化法制备生物基醋酸溶液的生物相回收策略
在生物质转化为生物燃料和生物化学物质(例如快速热解和非原位催化热解)过程中产生的生物水相包含大量有机物,导致对其处理的化学需氧量(COD)高。在这项研究中,我们证明了其催化转化为生物乙酸溶液并提出了其回收策略。我们发现稀释的生物水相(例如,C含量<0.5 wt%)可以选择性地(> 90%)转化为乙酸,溶液中存在不可检测的杂质。该溶液包含1.3–1.5 wt%的乙酸,可直接用于生物精炼厂中生物质的脱盐。这种回收策略增强了生物基经济的可持续性,并阐明了生物基乙酸的生产方法,这种乙酸已被公认为是一种智能的即插即用化学品。
