Hydrothermal Liquefaction of Lignin to Produce Bio-crude : Comparative Analysis of the Effects of Feedstock type and Operating Conditionson Bio-crude

2019

Master's thesis Renewable Energy ENE500 - University of Agder 2019 Lignin is one of the most abundant non-food biomass resources in the world today andseveral attempts are ongoingto harness its huge potential. Due to its rigid structure however, different processes are being experimented on how best todepolymerize it and maximizeits product streams. Some companies like Borregarrd have recorded successes in recent time,on producing vanillin from ligninusing a catalytic oxidation process, but still acknowledge that more products can be obtained from it. Hence, their quest to investigatethe energy potential of one of the lignin types in their product line; Lignosulfonate. The challenge is ther…
