石油圈中国石化新闻网讯 据路透社7月3日圣地亚哥报道，智利科学家说，从微藻生产的生物柴油可以驱动公共汽车和卡车并能把温室气体排放减少80%，从而可以减少像圣地亚哥那样的受污染城市的污染程度。 来自智利天主教大学化学工程和生物工艺系的专家说，他们已经培育了足够多的微藻来提取石油。微藻在去除水分和碎片以后能够转化为生物柴油。 智利天主教大学化学工程和生物工艺系研究员卡洛斯·赛斯说：“我们有关这个过程的新想法是打算从微藻中生产这种燃料。微藻是一种微生物。” 世界上大部分减少对石油依赖的生物柴油从大豆油衍生而来，生物柴油也可以用动物脂肪、菜籽油和棕榈油制成。 赛斯说，用微藻生产生物柴油的主要挑战将是生产足够量的微藻。智利拥有很长的海岸线，已经发现了各种各样的淡水和咸水微藻。智利的科学家时下正在设法提高微藻生长技术，使用有限能源的低成本来提高产量。 李峻 编译自 路透社 原文如下： Chilean Scientists Produce Biodiesel From Microalgae SANTIAGO- Biodiesel made from microalgae could power buses and trucks and reduce greenhouse gas emissions by as much as 80 percent, Chilean scientists said, possibly curbing pollution in contaminated cities like Santiago. Experts from the department of Chemical Engineering and Bioprocesses at Chile’s Catholic University said they had grown enough algae to fragment it and extract the oil which, after removing moisture and debris, can be converted into biofuel. “What is new about our process is the intent to produce this fuel from microalgae, which are microorganisms,” researcher Carlos Saez told Reuters. Most of the world’s biodiesel, which reduces dependence on petroleum, is derived from soybean oil. It can also be made from animal fat, canola or palm oil. Saez said a main challenge going forward would be to produce a sufficient volume of microalgae. A wide variety of fresh and salt water algaes are found in Chile, a South American nation with a long Pacific coast. The scientists are trying to improve algae growing technology to ramp up production at a low cost using limited energy, Saez said.
