Resumo: Chestnut shell (CS) is a by-product of some food sector companies. The aim of this study was to test the suitability of this material to be liquefied with polyalco- hols, optimizing the main liquefaction parameters in order to use the liquefied material for the production of high added value products. As the chemical composition of the fruit shell depends on the variation in the soil, cli- mate, and species, the chemical composition of CS was determined. Liquefaction was performed with 50:50 ethy- leneglycol:glycerol catalyzed by sulfuric acid. Different tests were carried out and several parameters were tested: par- ticle size, temperature 130–190°C, and time 15–120min. Chemical composition of CSs was determined. The main component found was lignin with 47.0%, which is higher than α-cellulose with around 20.5%, hemicelluloses 15.2%, and extractives in ethanol 8.8%. For the tested parameters, the best liquefaction yield was obtained at 190°C, 30 min, and a 40–60 particle size.
