摘要

系统地分析了木质纤维素生物质向化学中间体的分散预转化，包括技术、法律和经济方面。对14种生物质生产乙酰丙酸的案例研究表明，由于原料的性质，产率平均变化为+/−15.5%。由于高产率是经济运行的关键，这激发了针对特定原料的预处理技术。技术、法律和经济分析显示了建立分散式预处理装置的前景。与中央生物精炼厂的比较表明，规模经济可以通过更便宜的原料成本和量身定制的进料技术来抵消，这为化学品碳的分布式采购铺平了道路。

Benefits and Challenges for Decentralized Use of Biomass as Feedstock for Chemicals

A systematic analysis of the decentral preconversion of lignocellulosic biomass to a chemical intermediate including technological, legal, and economic aspects is presented. A case study of levulinic acid production from 14 types of biomass shows average variations of +/− 15.5 % in yield obviously due to the properties of the raw materials. As high yield is a key for economic operation, this motivates preprocessing technologies tailored to the specific raw material. Technological, legal, and economic analyses show the prospect to establishing decentral preprocessing units. A comparison with central biorefineries demonstrates that economy of scale can be counterbalanced by cheaper feedstock cost and tailored feeding technology, which paves the way for a distributed sourcing of carbon for chemicals.
