Summary: The effect of pH on the extraction yield of phenolic compounds from liquid phases recovered after the hydrothermal treatment of black liquor was studied using batch and continuous reactors. It was found that reducing the pH slightly improved the extraction of phenol and guaiacol, but greatly increased the extraction yield of syringol. Lower pH also hindered the hydrolysis of ethyl acetate during liquid-liquid extraction. The experiments confirmed the superior performance of the continuous reactor and the degradation of phenolic products at higher treatment temperatures.

Summary: In recent years, inorganic membrane filtration technology has emerged as a promising approach for treating papermaking black liquor and recovering lignin. However, the high cost associated with the preparation of most inorganic membranes hinders their industrial applications. In this study, a no-sintering, low-cost metakaolin-based geopolymer membrane (MGM) was developed using steel mesh as the substrate. By doping with slag, the MGM showed improved mechanical properties, microstructure, and separation performance. Compared to ceramic membranes prepared by sintering, the MGM offers cheaper raw materials and lower energy consumption, making it more suitable for industrial-scale applications.
