[Display omitted] •Pre-hydrolysis liquor is a promising feedstock to produce carbon microspheres (CM).•CM prepared from the PHL reduces the pollution load of the PHL significantly.•Sulfuric acid and lignin can significantly improve the formation of CM.•The functionalized CM showed good adsorption ca...
