摘要

马来酸酐氢化是生产 1,4-丁二醇的一种重要方法。然而，这种方法需要大量的 H2。因此，有人提出了利用生物质气化结合化学循环制氢技术（BGCLHP 路线）和天然气蒸汽重整（NGSR 路线）提供 H2 的顺丁烯二酸酐加氢法生产 1,4-丁二醇的新工艺。进行的生命周期评估表明，BGCLHP 路线对环境的影响小于 NGSR 路线。此外，还研究了技术经济分析，分析了资本和运营投资，证明了拟议路线与现有技术的可行性。以城市固体废弃物为原料，BGCLHP 路线的 1,4-丁二醇最低售价为 2245 美元/吨，表明该路线具有更好的经济效益。根据上述分析，BGCLHP 路线有可能促进 1,4-丁二醇产业更加生态友好和经济可持续发展。

Life cycle assessment and techno-economic analysis of maleic anhydride hydrogenation to 1,4-butanediol through biomass gasification coupling with chemical looping hydrogen production

Maleic anhydride hydrogenation is an important method to produce 1,4-butanediol. However, a large amount of H₂ is needed for this method. Thus, novel processes to produce 1,4-butanediol from maleic anhydride were proposed using biomass gasification combined with chemical looping hydrogen generation technology (BGCLHP route) and natural gas steam reforming (NGSR route) to provide maleic anhydride hydrogenation with H₂. Life cycle assessment was carried out, indicating that the BGCLHP route has a smaller environmental influence than the NGSR route. Additionally, techno-economic analysis was also studied to analyze the capital and operating investment, demonstrating the feasibility of the proposed route with existing technologies. Utilizing municipal solid waste as raw material, the minimum 1,4-butanediol selling price of the BGCLHP route was 2245 $/tonne, indicating it has a better economic performance. Based on the above analysis, the BGCLHP route has the potential to contribute to a more eco-friendly and economically sustainable 1,4-butanediol industry.
