綠色“生物燃料” [ 2006-12-12 16:13 ]
最近的期貨市場,國內(nèi)玉米期貨漲至階段性高點(diǎn)。原因嘛,“生物燃料”新概念 —— 用糧食加工酒精替代石油能源 —— 深入人心。
請看《中國日報(bào)》相關(guān)報(bào)道:For the first time in China's history, grain prices are rising
not due to a poor harvest or increasing demand but because of soaring
international oil prices.
To feed the nation's increasing appetite for energy, a huge amount of capital
including from overseas is chasing corn, soy and wheat for biofuel production; and pushing up prices to
record highs.
報(bào)道中的“biofuel”就是時(shí)下頗為熱門的“生物燃料”。作為最重要的可再生能源之一,“biofuel”指利用生物體制取的燃料,比如用玉米桿、玉米芯等發(fā)酵產(chǎn)生的酒精、沼氣,就屬于生物燃料。
顯然,“biofuel”(生物燃料)是個(gè)合成詞,前綴“bio-”指“生物的,生物體的”,與此相關(guān)的能源詞匯還有:bioenergy(生物能源)、bio-diesel(生物柴油)、bio-ethanol(生物乙醇)、bio-hydrogen(生物氫)、bio-gas(生物氣體,既“沼氣”)。
