Investigations Of Thermal Treatment Of Softwood Kraft Lignin Under Fractional And Ablative Pyrolytic Conditions, Dideolu J. Daniel

LSU Master's Theses

Lignin is second to cellulose in abundance among polymers in nature. Research studies on the development of new products and material combinations in which lignin degradation/conversion products are involved are still in their infancy, because fundamental knowledge about its structure, reactivity, and material and polymer behavior, is still lacking.

The objective of this research study was to investigate the complex thermal deconstruction and mechanistic behavior of a type of technical lignin, known as Kraft lignin, under depolymerization and to develop operating conditions for parameters influencing resulting product yields and operation of pyrolysis reactors.

Softwood Kraft lignin (s-KL) and methanol-fractionated (ex-KL) …

A Study Of Induction Pyrolysis Of Lignicellulosic Biomass For The Production Of Bio-Oil, Charles Edward Henkel

LSU Master's Theses

The increasing demand for energy coupled with a growing concern that the combustion of fossil fuels has on the environment, through the production of greenhouse gases, has created a demand for renewable energy sources. The demand for renewable energy, particularly liquid transportation fuels, can be met in part by the use of biomass based liquid fuels. There are several methods that can be used to produce biomass based fuels, but only thermochemical conversion (pyrolysis) can readily convert lignocellulosic biomass into a fuel-like liquid, bio-oil. The pyrolytic conditions for obtaining maximum liquid yields vary, but many of the criteria can be …
