Revisiting acidulation for tall oil and lignin manufacturing
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Sulfonated sporopollenin as an efficient and recyclable heterogeneous catalyst for dehydration of D-xylose and xylan into furfural [PDF]
, 2016 The natural acidity of sporopollenin, the biopolymer coating the outer walls of pollen grains, was enhanced by the sulfonation of its surface. Modified sporopollenin displaying sulfonic acid groups has been prepared, characterized by elemental analysis ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate
ChemPhysChem, EarlyView.Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Food Frontiers, EarlyView.Specific MAC bioactivities are associated with gut biotransformation. ABSTRACT Increasing the intake of microbiota‐accessible carbohydrates (MACs) has emerged as a promising nutritional strategy for preventing metabolic diseases. However, the consistency of their beneficial effects remains unclear, hindering their optimized application.
