摘　　要：在“双碳”目标背景下,通过对生物质热解液化制备生物油生产链条的生命周期技术经济评价,开拓生物汽柴油生产方式,为缓解我国原油进口“卡脖子”问题寻求新出路。从生物油厂建设到运营寿命期终止整个过程中,静态投资回收期为5.46年,动态投资回收期为7.45年,内部收益率为17%,累计净现值为2021.491万元。若项目生产成本、生产能力和销售能力与预期值相同,产品销售价格(生物柴油)不低于6105.81元·t^(-1)时,才能避免发生亏损。相对于电耗价格,该项目对原料价格敏感性更低,且需要生产规模大于1700 t才能实现项目的有效盈利。生物油厂进一步降低能耗和原料价格对其生存和发展至关重要,同时稳定廉价的原料供给也是企业竞争的关键所在。In the context of the"dual carbon"goals,exploring the production of bio-gasoline and bio-diesel through a biomass energy and pyrolysis liquefaction production chain holds significant potential.This approach could help alleviate China′s dependence on crude oil imports.Based on the construction of a bio-oil plant and its operational lifespan,the static investment payback period is 5.46 years,the dynamic investment payback period is 7.45 years,and the internal rate of return is 17%.The cumulative net present value is 20.21491 million yuan.To ensure profitability,the selling price of bio-diesel should not be lower than 6105.81 yuan per ton(assuming consistent production costs,production capacity,and sales capacity).The project is less sensitive to raw material prices than electricity costs,but requires a production scale greater than 1700 tons for profitability.Bio-oil plants should prioritize reducing energy consumption.An affordable and reliable raw material supply is crucial for the survival,development,and competitiveness of enterprises.
