Description
Summary:[Display omitted] •Direct catalytic conversion of industrial black liquor was achieved.•Pd0.5/Ni1Cu1-Mg30AlOx performed the reaction up to 5 times without deactivation.•Up to 99% of the phenols are extracted by hydrophobic ionic liquid.•The extraction is performed up to 3 times without loss in efficiency.•The global carbon-based yield is 11.8wt.% in pure phenolic compounds. The conversion, in a sustainable way, of paper industry wastes such as black liquor into value-added molecules is still challenging. Herein, a direct catalytic conversion of black liquor into an aqueous solution has been achieved at moderate temperature and pressure (
