Hydrothermally stable, hierarchically structured zeolites for the valorization of lignocellulosic biomass derived compounds by aqueous-phaseprocessing

Aqueous-phase processing (APP) offers the opportunity to selectively carry out energy efficient chemical transformations of biomass and derived compounds to valuable platform chemicals and liquid transportation fuels at mild conditions, i.e., T < 500 K and p < 5 MPa. APP further allows the direct conversion of wet biomass derived compounds, especially of low-value biomass from side- and waste streams. In addition, APP is particularly beneficial, since hydrogen required for the transformation to desired products can be generated during the process by reforming biomass-derived compounds such as formic acid. For the corresponding multi-step reactions bifunctional catalysts are required. In this respect, zeolites as acidic component and support have attracted considerable attention due to their outstanding catalytic performance allowing to convert biomass derived substrates. However, the hydrothermal stability of these materials under the typical reaction conditions of APP is rather low. In this context, the project aims at a systematic preparation of conventional and hierarchical structured zeolites with enhanced stability for the valorization of biomass derived compounds by APP.
