Abstract：
While wet waste hydrothermal liquefaction technology has a high biofuel yield, a significant amount of the carbon and nitrogen in the feedstock reports to the aqueous-phase product. Pretreatment of this stream before sending to a conventional wastewater plant is essential or at the very least, advisable. In this work, techno-economic and life-cycle assessments were conducted for the state-of-technology baseline and four aqueous-phase product treatment and monetization options based on experimental data. These options can cut minimum fuel selling prices by up to 13 % and life-cycle greenhouse gas emissions by up to 39 % compared to the baseline. These findings highlight the substantial influence of aqueous produce treatment strategies on the entire wet waste hydrothermal liquefaction process, demonstrating the potential for optimizing economic viability and environmental impact through further research and development of milder treatment methods and diversified by-product valorization pathways.
摘要：
而湿法废水水热液化技术具有较高的生物燃料产量,原料中大量的碳和氮向水相产物报告。在送至常规污水处理厂之前，对该流进行预处理是必不可少的，或者至少是这样。明智的。在这项工作中,根据实验数据，对技术状况基线和四种水相产品处理和货币化方案进行了技术经济和生命周期评估。与基线相比，这些方案可以将最低燃料销售价格削减高达13%，将生命周期温室气体排放量削减高达39%。这些发现突出了含水产品处理策略对整个湿废物水热液化过程的重大影响，通过进一步研究和开发更温和的处理方法和多样化的副产品增值途径，展示优化经济可行性和环境影响的潜力。
