Renewable resources are playing an increasingly important role in the chemical industry, so their efficient implementation is of increasing interest. The direct conversion of biomass into value chemicals is still a challenge due to the complicated and widely varying composition of biomass. The stepwise implementation of biomass via new platform chemicals such as furfuryl alcohol offers the advantage that already industrially established processes can be used for their production. In this work it could be shown that both ruthenium and copper catalysts are promising catalyst systems for the conversion of furfuryl alcohol to pentanediols. In this work, chromium-free copper catalysts were successfully tested, which achieve high selectivities for both 1,2- and 1,5-pentanediol. While copper catalysts are not sufficiently stable in aqueous media, under these conditions ruthenium catalysts are promising alternatives with high activity for the conversion of furfuryl alcohol to 1,2-pentanediol. The high activity of the catalyst system also makes it suitable for use in continuous reaction systems such as the trickle bed reactor possible. In this work, the conversion of furfuryl alcohol was experimentally investigated in both batch and trickle bed reactor experiments. Using experimental data, a kinetic model for the reaction was adapted, which in turn was used in a model of the trickle bed reactor. With the help of this model, it could be shown for the reaction in the trickle bed reactor that higher selectivities to 1,2-pentanediol can be attributed to a mass transfer limitation of hydrogen. Thus, both catalyst systems represent interesting alternatives to existing systems, wherein in the case of ruthenium catalysts, the use in the trickle bed reactor is recommended, while copper catalysts are suitable for use in batch reactors because of the lower activity. | English |
