Advanced Fractionation of Kraft Lignin by Aqueous Hydrotropic Solutions
Lignin is an underutilized high-potential biopolymer that has been extensively studied over the past few decades. However, lignin still has drawbacks when compared with well-known petroleum-based equivalents, and the production of tailored...
Valorization of Aloe barbadensis Miller. (Aloe vera) Processing Waste
Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as shampoo, soap, and sunscreen. However, the demand for these gel-based products has led to a surplus...
Topochemical fractionation of lignin and polysaccharides
Sugarcane bagasse is abundant agro-industrial waste that can be potentially utilized as a source of valuable compounds and biopolymers. In the present study, sugarcane bagasse from Brazil was fractionated employing an environmentally...
Topochemical characterisation of sugar cane internodes
Biomass pretreatments and subsequent conversion to fuels and materials involve a multitude of topochemical interactions. Detailed knowledge about changes in surface composition of biomass caused by pretreatments allows tailoring of biomass processing...
HyCellSolv pretreatment to enhance cellulose dissolution in water based solvents
Cellulose dissolution in water-based solvents is essential for processing of regenerated cellulose products such as fibres, films and particles. Cellulose dissolution in NaOH–urea aqueous solution has emerged as a simple and attractive...
Topochemical treatment of sugar cane bagasse for enzymatic hydrolysis of sugars
In this work, dilute alkaline and alkaline peroxide pretreatments were conducted in comparison with hydrotropic pretreatment to improve the delignification of bagasse prior to enzymatic hydrolysis. The surface chemical composition of bagasse...
Controlled depolimerization of cellulose via HyCellSolv
The degree of polymerization of cellulose is very relevant for physical and chemical properties of highly engineered biomaterials. The ability to control the level of depolymerisation to a final specific value opens...
Hydrotropic extraction of birch lignin
In this work an environmentally friendly hydrotropic process was used to extract lignin from industrial birch wood chips. Two hydrotropic treatments were performed, a conventional and a modified process. The lignins were...
Enhanced enzymatic saccharification of corn stover via topochemical treatment
Hydrotropic pretreatment using sodium xylene sulfonate (SXS) could remove lignin and xylan from corn stover to enhance enzymatic saccharification. Peracetic acid (PAA) treatment prior to the hydrotropic process [so-called modified hydrotropic pretreatment...
