| 摘要: |
BACKGROUND: Catalytic upgrading of fermentation-derived succinic acid or its derivates (succinic acid esters and succinic anhydride) to value added chemicals has received great attention recently. The aim of this work is to provide a process for the
production of tetrahydrofuran from succinic acid esters.
RESULTS: The hydrogenolysis of biomass-derived diethyl succinate was investigated over CuO–ZnO and CuO–ZnO/solid acid (HY, HZSM-5, SAPO-11 and Al2O3) catalysts in a fixed-bed reactor. Over CuO–ZnO, gamma-butyrolactone and 1,4-butanediolcan be selectively produced under appropriate reaction conditions,while the selectivity of tetrahydrofuran is relatively low due
to the weak acidity of CuO–ZnO. Over CuO–ZnO/HZSM, both the formed 1,4-butanediol and ethanol can be further converted to tetrahydrofuran and diethyl ether, while tetrahydrofuran is selectively produced over CuO–ZnO/HY. CuO–ZnO/Al2O3 and CuO–ZnO/SAPO exhibit slight improvements in terms of selectivity to tetrahydrofuran when compared with CuO–ZnO.CONCLUSION: CuO–ZnO/HY is an appropriate catalyst to produce tetrahydrofuran from biomass-derived diethyl succinate with high activity, selectivity and stability. Furthermore, Br？nsted acid sites with appropriate acid strength are responsible for the selective formation of tetrahydrofuran under the applied reaction conditions. |
