Catalytic hydrothermal liquefaction of industrial lignin to bio-oil
(North-West University (South Africa)., 2022)The negative implications of the world’s current fossil fuel systems are driving researchers to search for alternative energy resources. One of the alternative energy resources that has received attention is renewable fuels ... -
Characterization of lignosulphonate and its changes during purification
(North-West University (South Africa)., 2023)The world needs an environmentally friendly renewable resource that could satisfy future energy needs and lower the impact on climate change. This need has driven many countries to fund research into biomass and biomass ... -
Functionalising lignin in crude glycerol to prepare polyols and polyurethane
(Sage, 2019)In this work, crude glycerol liquefaction of lignins produced in the pulp and paper industry, as well as an organosolv lignin (sugarcane bagasse), was studied with the ultimate aim of preparing biobased polyols for ... -
Preparation of polyurethane foam from lignin and crude glycerol
(North-West University (South Africa), Potchefstroom Campus, 2018)The development and implementation of lignocellulose-based biorefineries which produce renewable fuels, chemicals and pharmaceuticals are expected to grow, but still face technological challenges. Economic feasibility could ... -
Rigid polyurethane foams from unrefined crude glycerol and technical lignins
(Sage, 2018)The need for green materials has driven interest in the preparation of rigid polyurethane foam (PUF) from various biomass types. The present study aims at increasing bio-based content by utilizing by-products from both ...
