Economic evaluation of biomass pyrolysis liquefaction technology based on life cycle assessment
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 cumula-tive net present value is 20.214 91 million yuan.To ensure profitability,the selling price of bio-diesel should not be lower than 6 105.81 yuan per ton(assuming consistent production costs,production ca-pacity,and sales capacity).The project is less sensitive to raw material prices than electricity costs,but requires a production scale greater than 1 700 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.
