Preparation, Characterization And Application Of Lignin Graft Copolymer As A Drilling Mud Additive

Water soluble lignin graft copolymer (LGC) was prepared from oil palm empty fruit bunch (OPEFB) fiber as a renewable biomass source. Beforehand, Kraft lignin (KL) was extracted by exploiting the OPEFB fiber Kraft pulping residue. The KL extraction was accomplished through the acid precipitation o...
