Butyl levulinate (BL) represents a novel diesel bio-blendstock and a versatile intermediate and solvent. The one-pot acid-catalyzed conversion of C6-feedstocks, employing -butanol as the solvent/reagent, implies the upgrading of low-cost or, even better, waste biomasses for developing prompt process intensification. In this paper, the one-pot butanolysis process has been studied, moving from model glucose and microcrystalline cellulose to a waste cellulose feedstock deriving from a real papermaking process. The performances obtained with this waste biomass have been optimized, achieving BL yields up to 46 mol %, adopting a high-gravity approach, in the presence of diluted sulfuric acid as the catalyst. The optimization was carried out also in the perspective of minimizing the alcohol etherification to dibutyl ether, and the feedstock carbonization to char by-product, whose characterization was performed to identify its suitable applications. The combined production of both BL as a valuable bio-fuel and char as an exploitable carbonaceous bio-material can pave the way to the development of the one-pot butanolysis of real cellulosic or lignocellulosic biomasses in an environmentally sustainable and integrated perspective, in agreement with the principles of the circular bio-economy.

关于乙酰丙酸丁酯生物混合物的见解:从模型糖到造纸厂废纤维素作为可持续催化丁醇分解工艺的原料
乙酰丙酸丁酯 (BL) 是一种新型柴油生物混合物和多功能中间体和溶剂。使用正丁醇作为溶剂/试剂的 C6 原料的一锅酸催化转化意味着对低成本甚至更好的废弃生物质进行升级,以开发快速的工艺强化。在本文中,研究了一锅丁醇分解工艺,从模型葡萄糖和微晶纤维素转向源自真实造纸工艺的废纤维素原料。利用这种废弃生物质获得的性能已经过优化,采用高重力方法,在稀硫酸作为催化剂的情况下,BL 产率高达 46 mol%。还从最大限度地减少醇醚化为二丁醚和原料碳化为炭副产品的角度进行了优化,对其进行表征以确定其合适的应用。 BL作为一种有价值的生物燃料和炭作为一种可利用的碳质生物材料的联合生产可以为从环境可持续和综合的角度开发真正的纤维素或木质纤维素生物质的一锅丁醇分解铺平道路,一致同意遵循循环生物经济的原则。
