Aerogels supported ionic liquid phase to catalyze the reaction between CO2 + Epoxides

Visiting Portuguese researcher in the HPP Group of the University of Valladolid is studying the comparison of using bulk ionic liquids as reaction solvent and catalyst for the coupling reaction between CO2 and limonene oxide, with the utilization of an ionic liquid phase adsorbed into alginate aerogels (SILP) in the frame of project AQACO2NV and […]

Cellulose processing with ionic liquids and supercritical CO2

Ionic liquids have been demonstrated to be highly effective solvents for biomass processing for the production of biofuels and chemical feedstocks from renewable resources, such as lignocellulosic biomass. This ability has attracted numerous studies of ionic liquids for the pretreatment and fractionation of lignocellulosic biomass. Nevertheless the high viscosity of ionic liquids which is greatly […]

[Thesis]: Study of the improvement of cellulose processing in ionic liquid by using carbon dioxide by Joana M.C. Lopes

Dr. Joana M. C. Lopes defended her thesis on Wednesday 5th October 2016 at the University of Valladolid. The capacity of the ionic liquids (ILs) of dissolving high concentrations of cellulose and/or lignin at relatively low temperatures makes them promising solvents for the processing of lignocellulosic biomass waste. Many applications have been proposed over the years: pre-treatment for fermentation […]

Intensified conversion of cellulose in ionic liquids and carbon dioxide

Cellulose esters, biodegradable polymers with a high number of applications, can be produced in homogeneous phase using ionic liquids (ILs). This group of salts are capable of dissolving high concentrations of cellulose in one step process and without catalysts. Nevertheless this process presents limitations such as product and reagents degradation due to long reaction times, […]
