摘要
对以菜籽油、麻疯树油和地沟油为原料制备的生物柴油进行了经济性分析。估算了生物柴油全生命周期的各子过程(种植、收获、运输、预处理,以及生物柴油的生产和配送)的成本构成。结果表明:原料种植或收购成本占总成本的76%～82%,扣除原料油支出的生产成本占总成本的14%～21%。影响成本的主要因素是油料作物种植及生物柴油生产。生物柴油的生产也受到甲醇价格的影响。以麻疯树油及地沟油为原料制备生物柴油的经济性均优于石化柴油,且麻疯树油路线更具竞争力。
An economic analysis was performed for biodiesel produced from rape seed oil,Jatropha curcas L oil,and waste oil throughout the biodiesel life cycle including the planting,harvesting,and transport,pretreatment,and biodiesel production and distribution.The life cycle assessment（LCA） cost analysis showed that the planting or purchase cost was about 76%～82% of the total cost,and the production cost excluding feedstock（rape seed oil,Jatropha curcas L oil and waste oil） was 14%～21% of the total cost.The planting and production costs accounted for the two largest shares of the total cost.The price of methanol affects biodiesel production.The Jatropha curcas L oil and waste oil based biodiesel fuels are cheaper than fossil petroleum based diesel.The Jatropha curcas L oil compete better economically.
