本文报道了可再生资源研究实验室在生物质转化为烯烃方面的进展。纤维素解聚的研究支持的引发/竞争性反应计划首先独立提出的Arsenau和Broido，但表明速率定律的特点是略高的表观活化能比报告的Bradbury等人。模型化合物甘油在超临界水中的分解的研究证明了两个主要途径。在较低温度下，异裂酸催化的碳正离子机理导致通过从甘油中消除水而形成丙烯醛。在较高的温度下，C → C键的均裂导致乙醛的优先形成。
This paper reports progress of the Renewable Resources Research Laboratory on the conversion of biomass to olefins. Research on the depolymerization of cellulose supports the initiation/competitive reaction scheme first proposed independently by Arsenau and Broido, but indicates rate laws characterized by somewhat higher apparent activation energies than those reported by Bradbury et al. Research on the decomposition of the model compound glycerol in supercritical water evidences two major pathways. At lower temperatures, a heterolytic acid catalyzed, carbonium ion mechanism results in the formation of acrolein by the elimination of water from glycerol. At higher temperatures, homolytic cleavage of CC bonds results in the preferential formation of acetaldehyde.
