不同原料制备生物柴油生命周期能耗和排放评价

建立了大豆、油菜籽、光皮树和麻疯树4种原料制生物柴油生命周期能源消耗和排放评价模型，并对其进行了生命周期能源消耗和排放评价。结果表明：与石化柴油比较，大豆和油菜籽制生物柴油生命周期整体能源消耗与石化柴油基本相当；光皮树和麻疯树制生物柴油的生命周期整体能源消耗比石化柴油低约10%；所有原料制生物柴油生命周期化石能源消耗显著降低，生命周期HC、CO、PM₁₀、SOx和CO₂排放降低，NOx排放升高。

Assessment of life cycle energy consumption and emissions for several kinds of feedstock based biodiesel

Life cycle energy consumption and emission assessment model for soybean, rapeseed, cornus wilsoniana wanaer(CWW), and jatropha curcaswas(JC) based biodiesel was established in this paper. And, life cycle energy consumption and emission assessment of soybean, rapeseed, CWW, and JC based biodiesel was conducted. Compared with conventional diesel, life cycle total energy consumption of soybean and rapeseed based biodiesel were basically equivalent to conventional diesel, life cycle total energy consumptions of CWW and JC were reduced by about 10%, and the life cycle fossil energy consumptions of all feedstock based biodiesel were remarkably reduced. Moreover, all of the life cycle HC, CO, PM₁₀, SOx, and CO₂ emissions except NOx of all feedstock based biodiesel were reduced.
