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 ... -
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 ... -
Separation of lignin from industrial prehydrolysis liquor using a solid acid catalyst
(ETA-Florence Renewable Energies, 2019)The concept of a biorefinery has been introduced in the pulp and paper industry in order to improve the industry’s profitability and competitiveness by generating new revenues from new products. Prehydrolysis liquor (PHL) ... -
A spent coffee grounds based biorefinery for the production of biofuels, biopolymers, antioxidants and biocomposites
(Elsevier, 2018)Spent coffee grounds are composed of lipid, carbohydrates, carbonaceous, and nitrogen containing compounds among others. Using n-hexane and n-hexane/isopropanol mixture highest oil yield was achived during soxhlet extraction ...
