Fischer, Auteur ; Andrew A. Peterson, Auteur ; Jefferson W. Tester, Auteur Année de publication : 2011 Article en page(s) : pp. 4420–4424 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Biomass Hydrothermal Carboxylate Résumé : We demonstrate a route for the production of C3 hydrocarbons from renewable biomass by the hydrothermal conversion of well-known fermentation end-products. Specifically, the major commercial C3 hydrocarbons, propane and propylene, can be obtained from butyric acid and 3-hydroxybutyrate (3HB) in substantial yields and industrially relevant productivities by hydrothermal decarboxylation. Butyric acid decarboxylates in supercritical water to give propane as the major product at 454 °C and 25 MPa. 3HB undergoes joint dehydration and decarboxylation in subcritical water to yield propylene at 371 °C and 25 MPa with yields of up to 48 mol %. Although catalysts may be found that increase yields and selectivities, these processes were demonstrated without any added heterogeneous catalysts, and have the further advantage of requiring no external H2 source.
