Abstract

See full text

Products extracted from black liquor include undissolved carbonized lignin and carbonized black liquor. The products further include solid carbon separated from the black liquor. Black liquor from an alkaline fractionation process is subjected to a hydrothermal carbonization process. Undissolved carbonized lignin is separated from the carbonized black liquor. The remaining carbonized black liquor is fed back into the alkaline fractionation process. The undissolved carbonized lignin is separated from the carbonized black liquor and purified.
