采用生命周期评价方法对玉米秸秆、稻壳和杨木3种生物质的气化合成航空煤油工艺路线进行环境影响评价。选取全球变暖、酸化、富营养化、光化学污染、人体毒性和固体废弃物6种环境影响类型,对3种工艺路线的全生命周期进行环境影响潜值计算。计算结果表明：系统全生命周期中生产阶段排放最多的是CO2,占比为69.13%~74.36%;运输阶段环境影响最小,在各环境影响潜值中占比不足7%;玉米秸秆是3种生物质中环境影响最小的原料,减少费托合成反应器的耗电量可降低玉米秸秆工艺的环境影响。
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.
