介绍了半纤维素溶液生产邻苯二甲酸酐新工艺的工艺合成、技术经济分析和生命周期评价。的生产包含六个步骤包括脱水木糖糠醛,还原的糠醛脱羰作用呋喃,糠醛氧化制顺丁烯二酸酐(MA)、Diels-Alder呋喃环加成作用,和马exo-4 10-dioxa-tricyclo 5.2.1.0 dec-8-ene-3, 5-dione其次是脱水,锅的甲基磺酸和乙酸酐的混合物(长),转化为乙酰显示和醋酸(AAD),和脱水AAD河畔。PAN的最低售价确定为每公吨810美元，约为油基PAN的一半。高价值产品的联合生产对于提高经济效益至关重要。生物质原料贡献了大部分成本。LCA结果表明，生物质PAN比油基PAN在减少气候变化和化石资源消耗方面具有优势，但需要更多的水。(c) 2015年美国化学工程师学会
The process synthesis, technoeconomic analysis, and life cycle assessment (LCA) of a novel route for phthalic anhydride (PAN) production from hemicellulose solutions are presented. The production contains six steps including dehydration of xylose to furfural, reductive decarbonylation of furfural to furan, oxidation of furfural to maleic anhydride (MA), Diels-Alder cycloaddition of furan, and MA to exo-4,10-dioxa-tricyclo[5.2.1.0]dec-8-ene-3,5-dione followed by dehydration to PAN in the presence of mixture of methanesulfonic acid and acetic anhydride (AAN) which is converted to acetyl methanesulfonate and acetic acid (AAD), and dehydration of AAD to AAN. The minimum selling price of PAN is determined to be $810/metric ton about half of oil-based PAN. The coproduction of high-value products is essential to improve the economics. Biomass feedstock contributes to the majority of cost. LCA results shows that biomass-based PAN has advantages over oil-based PAN to reduce climate change and fossil depletion however requires more water usage.
