摘要

挖掘废弃物（EW）和垃圾填埋气（LFG）是代表性的挖掘资源，为费托合成（FT）提供了充足的有机来源，而垃圾填埋场的周围环境进一步为光伏驱动的H2生产提供了机会。本研究提出了一个EW&；LFG-to-fuel （EW& lfgf）全生命周期系统，并通过Aspen Plus进行了仿真，利用ecoinvent数据库和文献数据对其技术-环境-经济性能进行了全面研究。系统的火用效率为66.70 %，主要用电量为FT和固体氧化物电解槽（SOEC）部分。生命周期评价（LCA）结果表明，渣油衍生燃料（RDF）和渣油衍生燃料（LFG）生产FT燃料带来的全球变暖潜势（GW）为41.77 kgCO2eq/GJ，而上下游生命周期过程特别是EW开采过程进一步推动了最终GW达到72.56 kgCO2eq/GJ。在燃料平净成本（LCOF）为33.23美元/吉焦（与之前报告的结果相似）的情况下，本研究报告的净现值（NPV）为23.21 M$。敏感性结果表明，向绿色能源供应结构的转变有助于未来将GW降低到72.56 kgCO2eq/GJ，并且当汽油和柴油价格下降~ 20% %时达到盈亏平衡点。

Unraveling the potential of Fischer–Tropsch fuel production from in-situ utilization of excavated waste and landfill gas with renewable hydrogen supply

Excavated waste (EW) and landfill gas (LFG), the representative excavated resources, provide sufficient organic source for the Fischer–Tropsch (FT) synthesis, and the surroundings of the landfill site further gives the chance for photovoltaic-driven H₂ production. In this study, an EW&LFG-to-fuel (EW&LFGtF) life-cycle system is proposed and simulated by Aspen Plus, and its techno-environment-economic performances are comprehensively investigated applying ecoinvent databases and literature data. The systematic exergy efficiency is 66.70 %, and the main consumer of electricity is the FT and solid oxide electrolysis cell (SOEC) sections. Life cycle assessment (LCA) results show that the production of FT fuel from residue-derived fuel (RDF) and LFG brings a global warming potential (GW) of 41.77 kg_CO2eq/GJ, while the up- and downstream life-cycle processes, especially the EW mining process, has further promoted the final GW to 72.56 kg_CO2eq/GJ. With a levelized cost of fuel (LCOF) of 33.23 $/GJ (similar to previous reported results), a net present value (NPV) of 23.21 M$ is reported in this work. Sensitivity results showed that the transformation towards the greener energy supply structure help decrease the GW to 72.56 kg_CO2eq/GJ in the future, and the breakeven point is reached when the gasoline and diesel price drops by ∼20 %.

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
