Treating black liquor with bio-oil acids for lignin recovery

The present invention describes a method intended for lignin recovery, said method comprising:- a first step of mixing a stream of black liquor with an acidic biomass stream for providing a mixed heterogenous stream;- a second step of separating the mixed stream in a separation unit for providing on...
