从木质纤维生物质中提取的乙酰丙酸具有作为平台中间体分子的潜力，可用于生产运输部门的可再生液体燃料。在此，我们报道了一种利用Rure/C催化剂将乙酰丙酸转化为γ-戊内酯(GVL)的催化过程，该催化剂比传统的Ru/C催化剂的活性要高得多。该双金属催化剂在硫酸存在下对乙酰丙酸的还原和甲酸的同时分解具有良好的稳定性，硫酸是碳水化合物制备乙酰丙酸的均相催化剂。技术经济分析结果表明，这一新工艺与GVL催化脱羧制丁烯和烯烃齐聚相结合，为木质纤维素生物质转化为液态碳氢燃料提供了一条经济有效的途径。
Levulinic acid derived from ligno-cellulosic biomass has the potential to be utilized as a platform intermediate molecule in the production of renewable liquid fuels for the transportation sector. Herein we report a catalytic process for the conversion of levulinic acid to gamma-valerolactone (GVL) using a RuRe/C catalyst that is significantly more active than a traditional Ru/C catalyst. The bimetallic catalyst is active for the reduction of levulinic acid and simultaneous decomposition of formic acid with good stability in the presence of sulfuric acid, the homogeneous catalyst commonly used in the production of levulinic acid from carbohydrates. Results from techno-economic analyses show that the integration of this new process with catalytic decarboxylation of GVL to butene followed by alkene oligomerization could provide a cost-effective route for the conversion of ligno-cellulosic biomass to liquid hydrocarbon fuels.
