| Description: | Lignin is the most abundant organic polymer in the plant world after cellulose. Most of the lignin extracted from lignocellulosic materials from the pulp and paper industry is burned to generate energy. Therefore, the main objective of this study was to gain a better understanding of production of liquid fuel from lignin and waste lignin from pulp and paper mill. Lignin was converting into useful liquid fuel via solvolysis liquefaction, esterification and transesterification process. The influences of transition metal sulfide catalysts (CuS; FeS2; MoS2) were investigated. The addition of transition metal sulfide based catalysts found that enhanced both productions of the oil and gas as well as contributed significantly to higher heating value (HHV) of ASL products. A high oil and gas yields of 82.1% and 2890cm3 was obtained with molybdenum disulfide (MoS2) at 250°C, 60 minutes reaction time. Comparison studies on production of liquid fuel from soda lignin and kraft lignin also have been investigated. Liquid fuel produced by solvolysis liquefaction of soda lignin possesses a better HHV and properties compared with liquid fuel produced from kraft lignin. A detailed product determination of liquid fuel was investigated via elemental analysis, pyrolysis GC-MS and FT-IR. The results revealed that the liquid fuel consist various types of functional groups and the analytical results shown the liquid fuel contains a high concentration of phenolic compounds. Besides, lignin was used as raw material to prepare solid acid catalyst for biodiesel production. Solid acid catalysts derived from lignin were used to catalyze esterification of oleic acid and transesterification of highacid value Jatropha oil to produce biodiesel. It achieved a 96% high conversion rate for esterification of oleic acid and 96.28% yield of methyl ester (biodiesel). In conclusion, the presence of catalyst can enhanced the conversion of lignin into useful chemical stocks. Lignin and waste lignin from pulp and paper mill can be used as green material to produce liquid fuel via solvolysis liquefaction and can be used as green catalyst to produce biodiesel from high acid value oil., Certification of Master s/Doctoral Thesis is not available,Ph.D. |
