2018-09-11T06:56:22Z urn:hdl:10324/31498 Production of saccharides from sugar beet pulp by ultrafast hydrolysis in supercritical water Martínez, Celia M. Cantero Sposetti, Danilo Alberto Cocero Alonso, María José Producción Científica Sugar beet pulp (SBP) is the major by-product in sugar industry. To make profit out of this undervalued residue, the FASTSUGARS process was proposed as a solution, combining the advantages of supercritical water as hydrolysis medium with very short reaction times in the so-called ultrafast reactors. Operating at 390 °C, 25 MPa and reaction times between 0.11 and 1.15 s it was possible to convert SBP into sugars and to obtain a lignin-like solid fraction. The highest yields of C-6 and C-5 sugars (61 and 71% w/w, respectively) were obtained at 0.11 s with the lowest yield of degradation products. The solid product obtained at 0.14 s was thoroughly analyzed by acid hydrolysis, TGA and FTIR analysis to prove its enhanced thermal properties and aromaticity. The FASTSUGARS process demonstrated being a versatile and promising technology to be integrated in the future biorefineries. 2018-09-11T06:56:22Z 2018-09-11T06:56:22Z 2018 info:eu-repo/semantics/article Journal of Cleaner Production, 2018 (In Press) 0959-6526 http://uvadoc.uva.es/handle/10324/31498 10.1016/j.jclepro.2018.09.066 eng https://www.sciencedirect.com/science/article/pii/S095965261832780X?via%3Dihub info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International Elsevier
