Abstract :

Abstract: The life cycle assessment method was used to evaluate the environmental impact of the gasification synthesis for the production of jet fuel from three types of biomass: maize stover, rice husk and poplar wood. Six types of environmental impacts, including global warming, acidification, eutrophication, photochemical ozone formation, human toxicity and solid waste, were selected to calculate the potential environmental impact of the three processes over their entire life cycles. The calculation results show that highest CO2 emissions in the production phase throughout the life cycle, with emission accounting for 69.13%-74.36%; minimal environmental impact during the transport phase, with each environmental impact potential accounting for less than 7%; maize stover is with the lowest environmental impact among the three biomass, and reducing the power consumption of the Fischer-Tropsch reactor can reduce the environmental impact of the maize stover process.
