Selective catalytic conversion of Lignocellulosic biomass components to chemicals

Tana, T. (2021) Selective catalytic conversion of Lignocellulosic biomass components to chemicals. PhD thesis, Queensland University of Technology.

Description

The PhD research program investigated a novel biorefinery process to convert entire lignocellulosic biomass to high value-added products. This green process involves: (a) the direct depolymerization of sugarcane bagasse to bioaromatics with high yield via one-pot oxidation-hydrogenation method, (b) production of the alkylated mono-sugars, and (c) simple carbohydrate-to-5-HMF conversion by a cheap and effective photocatalyst. The advantages of this approach include no acid, base or toxic chemicals are used, worked under relatively mild operating conditions, and the use of green solvents and solar energy. Products obtained from this project can be further upgraded to high performance materials and chemicals.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
